Abstract
In the underwater imaging system, When the light reflected from the surface of something tested through the water medium gets to the surface of the imaging lens or when the light through the air gets to the surface of the imaging lens, the reflection will happen, it leads that the light detectors receives the light less than before. The loss of light energy leads to the decrease of image illumination. Meanwhile, some of the reflected light becomes of stray light to the surface of image, and then that the contrast grade of image gets lower influences the quality of imaging. Hence, in order to minimize the impact of image quality, a system for the underwater antireflection film to improve image quality should be designed. This paper is based on the optical film-designed theory, for the blue-green light whose center wavelength is 532nm, the antireflection films of both air-optical glass interface and seawater-optical glass interface are designed, and the reflectivity curve and the their calculated results are given.
