Abstract:
1. A method of estimating a 3D surface of an object, wherein: (a) a pulse source emits wave pulses that travel to the object, reflect off of the object, and then travel from the object to a sensor by one or more diffuse reflections; (b) an occluder prevents the wave pulses from traveling in a direct line from the object to the sensor; (c) each respective wave pulse has a direction immediately before the wave pulse first diffusely reflects after being emitted by the pulse source; (d) the direction of the respective wave pulses varies from wave pulse to wave pulse; (e) the sensor captures streak images while the wave pulses arrive at the sensor after the one or more diffuse reflections; (f) a processor performs a calculation to estimate the 3D surface, wherein the calculation includes
