Abstract
Time-of-flight (TOF) based systems using light pulse compression are described and, in some cases, can help increase demodulation contrast. Further, light pulse shaping techniques are described that, in some cases, can help reduce phase non-linearity and distance-calculation errors. The techniques can be used, for example, in measurement systems, as well as imaging systems in which a time-of-flight and/or distance information is obtained. The time-of-flight and/or distance information can be used to reconstruct and display a three-dimensional image of a scene. The light compression techniques also can be used to provide reference signals.
