METHOD AND APPARATUS FOR THE READ-OUT OF A BOLOMETER ARRAY BY USING MULTIPLE BIAS PULSES

摘要

A method and apparatus to apply two or more bias pulses sequentially to each of the microbolometers in an array during a frame time such that the resulting temperature in each of the microbolometers of the array is uniform during the frame time. Then measuring resulting current signals associated with each of the two or more bias pulses to produce an average signal value to improve sensitivity and performance of the array as measured by noise equivalent power and noise equivalent temperature difference.
