The front lighting system mainly includes

The optical system of the headlight includes three parts: reflector, light distribution mirror and light bulb. The surface of the reflector is a spiral parabolic surface, which is a component used to reflect the road situation in front of the car. The headlights are installed on the car and mainly used for Road lighting at night. The headlights are located on the head of the car and are used to illuminate the road when driving at night.

It is mainly divided into two major systems, optical system and electrical control system. The optical system of the headlight includes three parts: reflector, light distribution mirror and bulb. ( 1) Reflector. The reflector, also known as the reflector, is used to maximize the light emitted by the bulb into a strong beam to increase the irradiation distance. ( 2) Light-matching mirror.

The optical system of the headlight is a combination of light bulb, reflector and light distribution mirror.With the development of high-speed vehicles, some countries have begun to pilot the three-beam system. The three-beam system is high-speed high-beam, high-speed near-beam and near-beam.

The lighting distance of the headlights is the basis for the design of car lighting science. The distance is long, the electric power is large, and the manufacturing accuracy requirements are high. On the contrary, the lighting distance is close, and the driving safety is poor.

The front lighting system is a combination of light bulbs, reflectors and light distribution mirrors. According to the structure of the front lighting system, the headlights can be divided into three types: semi-closed, closed and projected.

Four Elements of Ideal Optical System

The base points of the ideal optical system include object square focus and image square focus; object square main point, image square main point; object Square node, like square node. The base surface includes: the square focal plane and the square focal plane; the main plane and the square main plane; the square joint plane and the joint plane.

The optical system of the spectrometer is basically composed of four parts: lighting system: The main function of the lighting system is to guide the light emitted by the light source to the incident slit to ensure the uniformity and effectiveness of the light.

The intersection of the incident concentric beam is called the object point, and the intersection of the incident concentric beam is called the image point.The ideal optical system has the following properties: 1 One point (point) on the square of the optical system corresponds to one point (point) on the square. That is, after all the incident light emitted from the object passes through the optical system, the emitted light intersects at the image point.

The fourth imaging feature of an ideal optical system is no light loss. Light loss refers to the phenomenon that light weakens or disappears due to absorption, scattering and other reasons when passing through the optical system. There is no light loss in the ideal optical system, that is, the light can fully maintain its original brightness and intensity after passing through the optical system.

3 Any cross-sectional properties of the optical axis are the same; 4 The plane perpendicular to the axis has the same magnification in the same surface; 5 The position and magnification of two pairs of conjugated surfaces are known, or the position and magnification of a pair of conjugated surfaces are known, plus two pairs of conjugated points on the optical axis, which can determine the ideal optical system. Like.

2 Each straight line of the square corresponds to a straight line of the square is called the conjugate line; the corresponding surface is called the conjugate surface. 3 The conjugate surface of any plane perpendicular to the optical axis is still perpendicular to the optical axis. 4 For a pair of conjugate planes perpendicular to the optical axis, the transverse magnification is constant.

What is an infinite optical system

Infinity objective lens. The infinite optical system is to install a junction lens between the objective lens and the intermediate image plane to turn the intermediate light into a parallel beam. Theoretically, the beam can extend to infinity and is not limited by the length of the mechanical cylinder.

In the infinite distance correction optical system, the light from the specimen through the objective lens is not imaged in the objective lens, but enters the imaging lens as an infinite parallel beam, and the intermediate image is formed by the imaging lens.In the finite-distance correction optical system, the intermediate image is formed separately by the objective lens.

Infinity refers to an infinite optical system (also known as an infinite optical system). The objective lens and eyepiece of the microscope of this optical system are infinity optical designs. Infinity objective lenses and objective lenses cannot be used on microscopes of finite optical systems.

Objects in the infinite optical system cannot be directly imaged after being magnified by the objective lens. It needs to be imaged through the middle lens and observed after being magnified by the eyepiece. Because of its relatively small light loss, the infinite optical system is an optical system adopted by modern high-end microscopes.

What are the optical systems

Dispersion system: The main function of the dispersion system is to decompose the incident white light into a spectrum of different wavelengths and project it onto the light-sensitive plate.The dispersion system is usually composed of dispersion prisms, gratings and other optical components, which can disperse light of different wavelengths into different directions to form a spectrum.

Flat mirror, flat mirror combination system, parallel flat plate, etc. Planar mirror: A plane mirror is a kind of reflective optical component. The surface is flat and the light is reflected on the surface. The plane mirror can reflect light in different directions, but does not change the size of the image.

Optical system refers to a system that is composed of a variety of optical components such as lenses, reflectors, prisms and optics in a certain order. It is usually used for imaging or optical information processing.

Optical system. Some Bo's glasses can also move up, down, left and right; some are equipped with a lock aperture or needle.The aperture can be narrowed or pinhole appendage can be added when observing the small mineral interference map to block the interference of the surrounding minerals and make the interference map clearer. Boer's mirror mainly plays the role of magnification.

The optical system of the headlight includes three parts: reflector, light distribution mirror and light bulb. The surface of the reflector is a spiral parabolic surface, which is a component used to reflect the road conditions in front of the car. The headlights are installed on the car and are mainly used for road lighting at night. The headlights are located on the head of the car and are used to illuminate the road when driving at night.

The working principle of the optical system is equivalent to

convex lens imaging. This is the principle of the camera - because the distance is outside the 2x focal length of the convex lens, and between the focal length and the 2x focal length on the other side of the convex lens, it becomes an inverted and reduced real image.

It should be B. Your question is not specific enough. The functions realized by different optical systems are also different, but the front optical systems of most instruments realize the function of convex lenses into real images.

The optical system is equivalent to the eyes of the camera, which is closely related to operation skills. It will be described in detail in the following sections of this chapter. The photoelectric conversion system is the core of the camera, and the camera tube or solid camera device is the "heart" of the camera. The content of this part will be introduced in the third chapter.

ccd accumulates a corresponding proportion of charge according to the strength of the light. The charge accumulated by each pixel is moved point by point under the control of the video timing. After filtering and amplification, it forms a video signal output. When the video signal is connected to the video input terminal of the monitor or TV, you can see the same video image as the original image.

The working principle of the surveillance camera is that the optical image generated by the light (scene) through the lens (LENS) is projected onto the surface of the image sensor, and then converted into an electrical signal.

Transform optical image signals into electrical signals for easy storage or transmission. When we photograph an object, the light reflected on the object is collected by the camera lens to focus on the light surface of the camera device (such as the target of the camera tube), and then the light is converted into electrical energy through the camera device, that is, the "video signal" is obtained.
