Fabrication and Performance Test of TGS Pyroelectric Detectors
TGS 초전검출기 제작 및 성능검사
Abstract
Pyroelectric TGS(triglycine sulfate) detectors, whose thicknesses are 0.1mm and 0.2 mm, are fabricated using the grown TGS crystals from aqueous solution. The outut power and noise from these detectors are measured as a function of chopping frequency in the range from 10Hz to 160Hz with the interval of 10Hz. Response time, responsivity and detectivity are derived from the measured output power and noise of the detectors. The results show that the response time is about 15ms, resposivity is 100V/W at 10Hz and the detectivity at the maximum spectral wavelength D{{{{ lambda }}P* is about 10 cmHz1/2w-1.
