However, because of the work-band restrictions of the traditional LLL image intensifier test system, it s unable to test ultraviolet (UV) and near-infrared bands of the image intensifier; therefore it s necessary to develop a new test system to complete the wide spectrum of the image intensifier performance measurement.

Study on optical film thickness monitoring system by wideband spectrum based on LabVIEW;

A comprehensive monitoring system with wideband spectrum by fiber optic spectrometer;

Based on the new configuration of optic stress system, we need to design a wide bands and long focal night vision collimating lens.

Optical design of apochromatic objective of wide spectral and long focal

With the rapid development of charge coupled device , optical system of wide spectral is widespread availability in the field of space optical sensing, groundbase target tracking and civil security monitoring.

Under different uniform temperature field,the effects on spectral bandwidth and signal noise ratio(SNR) of the HSI due to the slit s width changing are deduced.
