Abstract
Aspects of the present disclosure involve example systems and methods for remote sensing of objects. In one example, a system includes a light source, a camera, a light source timing circuit, an exposure window timing circuit, and a range determination circuit. The light source timing circuit is to generate light pulses using the light source. The exposure window timing circuit generates multiple exposure windows for the light pulses for the camera, each of the multiple exposure windows representing a corresponding first range of distance from the camera. The range determination circuit processes an indication of an amount of light captured at the camera during an opening of each of the multiple exposure windows for one of the light pulses to determine a presence of an object within a second range of distance from the camera, the second range having a lower uncertainty than the first range.
