Uniform illumination image capture
Methods and systems are provided for capturing an image having uniform illumination over a range of distances. The system may include a light source, a light sensing array, and an electronic circuit. The method may involve selecting a range of distances from the system, causing the light source to generate a light pulse with a modulated decay, and using the light sensing array to sense an integrated intensity of a reflected light pulse during an exposure time. The reflected light pulse may be provided by the generated light pulse reflecting from an object located at an object distance within the range of distances. The exposure time may be controlled based on the range of distances and the modulated decay such that the integrated intensity of the reflected light pulse is substantially independent of the object distance.
