Abstract
Methods for linearization of photodetector response include establishing one or more static calibration coefficients based on comparison of test photodetector response to a linear reference photodetector. In some examples, dynamic calibration coefficients are determined based on average photodetector signals. In some applications such as FTIR, linearized ratios are obtained with a single calibration coefficient.
Claims20
An FTIR system, comprising:
- a photodetector;
- a memory device storing at least one calibration coefficient associated with the photodetector;
- and
- a processor coupled to receive a photo-signal responsive to irradiation of the photodetector and linearize the photo-signal based on the at least one calibration coefficient.
