ABSTRACT:
A readout system for receiving return signals originating from one or more energy pulses fired toward a scene. The system includes a first mechanism for detecting energy received from the scene and providing a first signal in response thereto. A second mechanism times a rising edge and a falling edge of a pulse contained in the first signal and provides a second signal in response thereto. In a specific embodiment, a third mechanism determines characteristics of the pulse based on the second signal, which include characteristics, such as pulse width, pulse intensity, and/or pulse centroid, sufficient to generate an image of the scene.
