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.
