1. An active pulsed four-dimensional (4D) camera system for acquiring information about a scene comprising: at least one emitter configured to generate and emit light within a defined frequency range throughout a field of view of the scene, wherein the emitted light is an active sequence of pulses; an array of detectors configured to receive light within the defined frequency range for a field of view of the array, the field of view of the scene defined by the field of view of the array and each detector in the array having an individual field of view that is a different subset of the field of view of the array; control circuitry operably coupled to the at least one emitter and the array of detectors and configured to cause the at least one emitter to begin to emit the active sequence of pulses at a first time and to cause the array of detectors to begin to receive light at a second time after the first time in an emitter/detector cycle, wherein the control circuitry is configured to vary an elapsed time between the first time and the second time in K successive emitter/detector cycles, wherein K is greater than 4 and a total elapsed time of the K successive emitter/detector cycles is less than 50 microseconds; and a processing system operably coupled to the array of detectors and the control circuitry and configured to: generate and store digital information corresponding to light received by each detector in the array of detectors, the digital information for each detector in the array of detectors being sampled and stored in one of K frame buffers corresponding to one of the K emitter/detector cycles, and analyze the digital information for each detector and construct a representation of at least a portion of the scene based at least in part on time-of-flight (TOF) data in the digital information corresponding to the sequence of pulses received by different ones of the K frame buffers and on relative timing differences of the sequence of pulses for each of the K emitter/detector cycles.
