Diffusive-Probabilistic Model for Inter-Pixel Crosstalk in HgCdTe Focal Plane Arrays

Blog Article

A closed-form probabilistic model for inter-pixel crosstalk in planar HgCdTe focal plane Pull Pin arrays is presented, providing simple expressions of crosstalk as function of device parameters like the pixel pitch, the absorber thickness, and the extension of the copyright depleted region.The method is effective in particular for performing parameter sensitivity studies on inter-pixel crosstalk, as an alternative to large-scale numerical simulations.The model is validated against Mastectomy Clothing three-dimensional combined optical and electrical numerical simulations, considering realistic, non-monochromatic illumination.
