Paper Abstract

Low-level-light (LLL) sight devices measurement technologies based on multiple environments testing conditions are always concerned by military equipments manufacturers. Because vibration, shooting, shock, drop and high low-temperature environment, etc. are under loaded function, the machinery, optics structure and electric performance parameter change to make LLL sight instrument, causing the LLL sight instrument can't be worked and used normally while taking aim. We have designed the measure and test system of LLL sight instruments under multiple environmental experimental conditions, provided and made up the operation principle of the detection system by CCD. Have analyzed the image of LLL sight devices, have brought forward algorithm of median filter, and have already confirmed its accurate number value. Have combined actual project application, the measure precision which is less than 0.05 mil. And the measure range which is greater than 40 mil. It can meet the project requirements.
