METHOD AND DEVICE FOR THE SPATIALLY RESOLVED MEASUREMENT OF RADIATION SIGNALS

摘要

A measuring method and a measuring device for the spatially resolved measurement of radiation signals, in particular light signals, wherein RIfS-measurements can be carried out. At least two locations are imaged onto a detector in a spatially resolved manner by means of a spatial modulator, and either by means of a Hadamard transformation the intensity difference is calculated between the two locations from the detected signal by modulating the locations using the same Hadamard sequence, wherein one of the Hadamard sequences at one location is inverted compared to the other sequence at the respective other location, or the intensity difference between the two locations is calculated from the signal detected from the two locations with the same frequency by means of a Fourier transformation, wherein the signals are amplitude-modulated, but phase-shifted relative to one another.
