| Abstract: | A small-sized fiber grating spectrograph which can measure solar ultraviolet spectrum from 250 nm to 450 nm is introduced. It is C-T structure, the detector is composed of self-scanning photodiode array of HAMAMATSU company. The radiance calibration is introduced. The detector driver circuit and sample circuit design is also introduced. The relation between detector integrating time and signal-noise ratio is discussed. |
