Abstract

The adaptive transfer function concept analyzes the various factors contributing to the uncooled microbolometer FLIR camera performances, and describes a series of solutions to control in real time its transfer function for optimal performances. The paper describes the entire camera concept, elaborating in more details the following subjects: 1. The time domain filter used to improve the SNR and its control function, 2. The two dimensional filter used to remove the DC and the low frequencies components, 3. The supplementary filter used to reduce one over f law power noise on vertical direction, 4. The dynamic range compression and its control function.
