Light amplification panel (LAP) based on laser principle is put forward in this paper. The LAP is coupled between the camera and eyepiece of the night vision devices to realize image intensification. The quality of imaging in low level light is gained enhancement. After analysis on principle of LAP, its gain, detection capability, imaging performance, noise and bandwidth are calculated theoretically. Laser media arranged alternately amplifies signals of different wavelength, broadening the bandwidth and also realizing night vision color imaging by physical mode.

According to the optical-electric properties of liquid crystal, an eye controlled focus (ECF) anti-glare imaging detector is designed. Considering the existed concept of point metering controlled by the eye, a new concept of photometry, point-by-point single-pixel metering controlled by the eye, is brought forward. The method of ECF in the detector is researched. Firstly the pupil’s image is attained, and then the detector focuses with the focused function. Besides, a distinct image and a vague one are processed. The focused function values of the two images are 8.5057×103 and 7.2381×103 respectively.

Based on the electro-optical property of liquid crystal (LC), an eye controlling anti-glare detector is designed in this paper. According to the transmission characteristics of SONY- LCX029 materials, the principle and working mode of anti-glare are described. The detector can get the object’s images by eye-controlling focus (ECF) module and exposure metering module. The LC can change each pixel’s transmission with the reasonably designed control circuit so that the glare is restrained. An experiment of SONY-LCX029 LCD (liquid crystal display) transmission changes with the gray level proved that the transmission of the LCD changes from 1.28% to 25.60%, reducing 2 orders of magnitude of strong light at least.
