Abstract

Disclosed is a method for determining a pixel gray scale value image, particularly for a multi-dimensional image system. According to said method a first modulation signal (M) which is emitted at the emitting end and is reflected on an object that is to be recorded is correlated with a second modulation signal (M) and is recorded at the receiving end based on at least two correlation signals (Ua, Ub or Ia, Ib) that are proportional to the respective received first modulation signal (M). One of said modulation signals (M, M) is phase shifted in several phase steps (ψk) at the emitting or receiving end and a differential signal (D) is determined for each phase step (ψk) based on the correlation signals (Ua, Ub or Ia, Ib,) and a pixel gray scale value (P) is determined based on said difference signal (D) independently of interfering signals.
