The Unitormity and Linearity of Infrared Spectral Response of Decector

The Uniformity and linearity of spectral response of infrared detector are considered as the important parameters to evaluate the characteristics of infrared detectors,The Optic Metrology Station is currently engaged in a programme of work to Measure the uniformity and linearity of response of infrared detector.which includes some work in the atmospheric windows,and the Station also busy with the evaluation for some commercial infrared detectors,which are expected to beidear detectors and to be used to transfer the infrared spectral responsivity.The paper described the facilities.measuring methods and results,and evaluated some infrared detectors working in different wave ranges to transfer quantity value.
