1. An optical surgical system with compensation for angular distortions, the system comprising:
a plurality of light emitters disposed at a working end of a surgical instrument on a first surface;
a plurality of light sensors disposed at the working end of the surgical instrument on a second surface opposing the first surface, the first and second surfaces disposed on a pair of non-parallel jaws with an angle (θ) between the first and second opposing surfaces; and
a controller coupled to the plurality of light emitters and the plurality of light sensors, the controller configured to:
model a non-pulsatile illumination pattern according to the intensities of individual emitters of the plurality of light emitters,
compare the non-pulsatile illumination pattern according to the model against a non-pulsatile illumination pattern detected using the plurality of light sensors, and
vary the intensities of the individual emitters of the plurality of light emitters based on the comparison of the non-pulsatile illumination pattern according to the model and the non-pulsatile illumination pattern detected using the plurality of light sensors until angular distortion has been removed.
