Measurement of spectral response of ultraviolet detector using photoacoustic spectroscopy

In order to obtain the spectral response of ultraviolet detector more exactly,a measuring system of spectral response,based on the photoacoustic spectroscopy with the photoacoustic detector of high sensitivity as a reference one,was established.Due to this technique,the relative spectral response of two kinds of ultraviolet detector was measured.The experimental results show that this measuring system is simple,reliable and easily repeated.Between the 250nm and 450nm,it can exactly measure the spectral response of ultraviolet detector.Furthermore,it also can be used to measure the spectral response of visible photo-electronic detector and analyse the photoacoustic spectroscopy of solids samples.
