Development Status of Space Spectral Imaging and Integrated Optical Thin Film Technology

With the development of space spectral imaging technology to higher accuracy and wider spectrum,long linear and large array detectors have become the main photoelectric sensors in full spectrum Multi-spectral(Hyper-spectral and Ultra-spectral) imaging spectrometers.Based on the analysis of the development status of space spectral imaging technology,this paper introduces the development process and current situation of space integrated optical thin film technology,and forecasts its future development trend.
