For the case where the active area of the detector is square, use a circular detector of equal area. This will yield a close numerical solution. Knowing the responsivity of a detector and the net power exchange from the source, the output signal Vout can be estimated as:7=RAF<AG8AEAH<AI8AE_AFAJ<AK8AEAHAL<AM8AE_AJAN<AO8AEALAP
