The influence of optical component quality on the signal-to-noise ratio of infrared optical systems

With the development of modern science and technology, stricter requirements have been put forward for optical systems. However, the limitations of optical component processing technology and usage environment inevitably result in "defects" such as impurities, scratches, pits, and surface pollution. The most common stray light in optical systems enters the optical system at an angle outside the field of view, and is then scattered by mechanical components into the field of view, entering the subsequent optical path. This scattering is usually easily eliminated.

However, it is much more difficult to eliminate the light that first enters the lens or reflector and then scatters from the surface of the optical element into the field of view of the optical system. This scattering is usually caused by two factors:

(1) Scattering caused by surface scratches, pits, or other defects greater than the wavelength of light compared to the wavelength of light;

(2) Due to the fact that high-quality optical surfaces have almost no defects, scattering comes from small surface irregularities caused by polishing or other processes.

In general, due to the limitations of modern processing technology, optical components inevitably leave various defects during the substrate processing process. In addition, the surface of optical components can also be contaminated during use.

This defect and surface pollution can cause varying degrees of scattering of human light, not only increasing the loss of light energy, but also deteriorating the imaging quality of infrared optical systems, thereby affecting the extraction and analysis of infrared light. The infrared optical system emits target signals, It is necessary to study the effects of optical component defects and surface contamination on the stray radiation performance of the system.
