Claim:
1. A method comprising: determining time-of-flight data for at least one pixel of at least one time-of-flight sensor configured with at least one retro-reflector, wherein the time-of-flight data includes a first distance from the at least one time-of-flight sensor to at least one point of at least one surface, and a second distance from the at least one point to the at least one retro-reflector; determining other time-of-flight data for one or more neighboring pixels which are neighboring the at least one pixel; determining at least one range distance to the at least one point of the at least one surface by causing, at least in part, a factoring out of the second distance from the time-of-flight data by using the other time-of-flight data; and causing, at least in part, a reconstruction of the at least one surface using the at least one range distance.
