Abstract: Aspects of the present disclosure provide systems, methods, devices, and computer-readable media for interference filter correction based on angle of incidence.

Based on this spectral shifting, the intensity of the transmission spectrum is corrected. An image corresponding to the corrected intensity of the transmission spectrum may be generated.
