| Abstract:In this paper, the performance and application of hyperspectral infrared detector are introduced. Compared with the same type of foreign hyperspectral infrared detector, such as signal-to-noise ratio, dark current and readout noise, the spectral response of short wave detector reaches 0.4-2.6 μm and the average quantum efficiency is more than 75% after substrate removal process 99, and the half well signal-to-noise ratio can reach 1600. The performance is better than that reported by similar devices abroad and can meet the hyperspectral application in China. |
