Scattering effect analysis and elimination method for RC reflective optical system

RC reflective optical system is a commonly used optical imaging system, which has the advantages of high resolution and high sensitivity, and has been widely used in scientific research and industry. But in use, RC reflective optical system will have some scattering effects, such as uneven light intensity, atomization and other problems, affecting the imaging effect and stability of the system. Therefore, it is necessary to analyze the scattering effect of RC reflective optical system and take corresponding elimination methods to improve the imaging quality and stability of the system.

1. Scattering effect of RC reflective optical system

RC reflective optical system consists of a mirror, a convex lens and a detector, etc. In the optical imaging process, light is reflected by the mirror after passing through the lens, and then imaged on the detector through the lens. In this process, there will be some scattering phenomena, such as:

1, uneven light intensity: due to the uneven surface of the mirror, mirror surface absorption and scattering and other reasons, resulting in the beam after the reflection of the mirror will produce scattering phenomenon, so that the light is not concentrated or crossed, resulting in uneven light intensity.

2, mirror surface atomization: In the use of RC reflective optical system, due to the influence of environmental temperature and humidity and other conditions, the surface of the mirror may produce water mist, oil film and dust and other impurities attached, thus affecting the optical characteristics of the surface of the mirror, resulting in the surface atomization of the mirror, so that the reflection efficiency is reduced.

3, convex lens surface atomization: During the use of RC reflective optical system, due to the external environment, such as high temperature and humidity, dust and other reasons, the surface of the convex lens may also produce impurities such as water mist, oil film and dust attachment, thereby affecting the optical characteristics of the lens surface, resulting in the lens surface atomization, so that the lens transmittance decreases.

2. Elimination method of RC reflective optical system

In order to eliminate the scattering phenomenon of RC reflective optical system and improve the imaging quality and stability of the system, the following measures need to be taken:

1, Optimize the design of the mirror surface characteristics. A mirror with good surface quality, high reflectivity and low absorption should be selected, and the data characterization must be accurate, so as to avoid the phenomenon of uneven light intensity. In actual application, the surface characteristics of the mirror can be adjusted according to different usage scenarios.

2, timely cleaning and maintenance of the mirror surface. The mirror surface of the RC reflective optical system should be cleaned and maintained regularly to avoid the influence of impurities such as water mist, oil film and dust on the mirror, so as to ensure the reflection efficiency and imaging quality.

3. Properly reduce the humidity and temperature of the environment. Humidity and temperature are important factors affecting the surface atomization of mirrors and lenses, so measures should be taken to reduce ambient humidity and temperature, such as installing air conditioning, ventilation and so on.

4, increase the anti-fouling performance of mirrors and lenses. The anti-volatility and anti-adhesion properties of the mirror and lens can be increased by coating the surface with anti-viscosity materials or lens film, so as to avoid the adhesion of impurities on the surface of the mirror and lens resulting in atomization.

In short, for the scattering phenomenon of RC reflective optical system, we should start from the optimization design, timely cleaning and maintenance, reduce the humidity and temperature of the environment, increase the anti-fouling performance of the mirror and lens, so as to eliminate the scattering effect of the system and improve the imaging quality and stability of the system.
