Use of computer modeling to predict performance and production yield of photodiode arrays has been previously reported. In this earlier work, a narrow, collimated slit source of radiation was assumed to be normally incident on the back side of a generalized photodiode array. An analysis of carrier diffusion in the array led to values for diode quantum efficiency and line spread function, which in turn led to values for absolute signal responsivity, noise equivalent irradiance, and modulation transfer function. A further modeling extension is reported here which brings the model a step closer to real life electro-optical systems. The former idealized radiation input to the focal plane is replaced by a radiation blur circle generated by a ray trace model. The ray trace model simulates radiation spatial, angular, and spectral characteristics of an operational frontend optics module. A methodology for interfacing ray-trace models to carrier diffusion models is considered here, with attention to some radiation transport details which can significantly influence model predictions.
