Abstract
A method of measuring a field-of-view (FOV) of an optical sensor includes the steps of: (a) uniformly illuminating a FOV of the optical sensor; (b) moving, at an angle of motion, a slit across the FOV and illuminating the optical sensor through the slit; (c) measuring an optical response of the sensor through the slit, at evenly spaced positions of the moving slit; (d) changing the angle of motion and repeating steps (b) and (c); (e) repeating step (d) for equally spaced angles of motion; and (f) constructing a two-dimensional map of the FOV of the optical sensor, after completing step (e). Constructing the two-dimensional map of the FOV includes filtering the measured data using a filtered backprojection algorithm, and interpolating among the filtered measured data to form the two-dimensional map.
