An indium antimonide (Insb) photoconductive cell is used in a production line to count the number of products on a moving conveyer belt at room temperature. Figure 2 shows the spectral response of the detector. Calculate the incident radiation at 5 um to produce S/ration 30 dB while having area of 1 mm? Use Figure to find normalised detectivity D. Consider Af = 1. NE 1011 Pus 5 PbS (-196°C) 2 1 1010 Detectivity D". cm. Hz"/W 5 2 100 1 PbSc 5 2 7. InSb 10" 5 2 1 1 1 РЬТе 10 2 3 5 0 7 4 Wavelength.
