Infrared channel window of the photoelectric device will be caused imaging blur due to frosting and fogging, which will affect the use of the equipment. In order to solve this problem, the infrared photoelectric equipment channel window is analyzed, on the basis of heating technology in high resistance is given on the silicon substrate guided electric plating metal gate of the heated solution. And the test are carried out. The experimental results of heating function, performance, safety and environmental adaptability show that this method can effectively solve the problem of frosting and fogging in infrared channel window.
