Basic approach to define signal-to-noise ratio for adjacent pixels for an uncooled micro-bolometer FPA detector

摘要

To define the ratio of the signal of the desired pixel and the noise of adjacent pixels, noise and signal sources are theoretically identified. While defining these values, atmospheric attenuation, losses at transmitting surfaces and wave characteristics of light are considered. For presentation purposes, a standard NATO target is chosen as source object. The model has been developed for a simple optical design which is intentionally left defective to better address effects of aberrations to signal to noise ratio of adjacent pixels especially caused by diffraction.
