Abstract: Because of the limits of illumination in the cars, the drivers can't observe clearly at night, which greatly increases the driving dangers. Car night vision system is a novel technology that helps to increase the driver's observation distance and is not subjected to the adverse conditions such as snow and rain. Novel car night vision system has has been widespread concerned. However, the change of temperature has a great impact on night vision system. Chalcogenide glass has a high-transmittance rate in infrared spectrum regions, and also has the advantages of small temperature coefficient of refractive index and modling which is suitable to car night vision systems. The features of chalcogenide glass were analyzed, the advantages of chalcogenide glass in night vision system were summarized. Car night vision systems using chalcogenide glass were presented.
