Abstract
A system and method for compensation of angular distortions in a system utilizing light emitters and light sensors disposed on non-parallel jaws may include determining a first point at a first side of a region of interest and a second point at a second side of the region of interest, determining a linear curve including the first and second points, and utilizing the linear curve to remove the angular distortion from the region of interest between the first and second points. A system and method for compensation of angular distortions may alternatively include modeling a non-pulsatile illumination pattern according to the intensities of individual emitters, comparing the pattern according to the model against a non-pulsatile illumination pattern detected using the light sensors, and varying the intensities of the individual emitters based on the comparison until angular distortion has been removed.
