Abstract: A method for determining a distance to a target comprises: receiving a bitstream of binary digits corresponding to a time-varying signal based on light transmitted by a light source being reflected by the target, wherein each binary digit in the bitstream is defined based on the time-varying signal at a time instance represented by the binary digit being above or below a threshold; comparing the bitstream to a set of stored reference bitstreams, wherein the set comprises pairs comprising a first reference bitstream and a second reference bitstream representing a common distance to the target, wherein the first reference bitstream is phase-shifted in relation to the second reference bitstream; and determining the distance to the target based on selection of a pair of reference bitstreams based on said comparing.
