UV focal plane array device relative spectral response measurement technology research

摘要

Spectral response is one of the important technological parameters of the detector, along with the development of the ultraviolet detector technology, accurate measurement of UV detector spectral responsivity is becoming more and more important. This paper analyzes the ultraviolet focal plane array relative spectral responsivity measurement principle, using the substitution method of measuring ultraviolet focal plane array detector relative spectral responsivity, and established a calibration device for relative spectral response of UV focal plane array. The relative spectral response of UV focal plane array device was obtained, can be seen from the curves, UV focal plane array device from 250 nm to 290 nm spectral response range, the peak response near 270 nm, Show that the array sun-blind characteristic of a device. The uncertainty of analysis results showed that UV focal plane array device relative spectral response measurement uncertainty of calibration device is about 3.6%, can meet the demand of high precision measurement.
