Reliable application of spatial light modulators (SLMs) as programmable diffractive optical elements
requires a thorough calibration. In this paper, we propose a method for calibrating SLMs based on the
evaluation of Fresnel images. Fresnel images generated by a binary phase diffraction grating consist of
binary irradiance distributions whose visibility depends on the phase modulation. By displaying on our
device a diffraction grating with a binary phase step along one direction and a linearly increasing phase
along the orthogonal direction, we perform a complete phase calibration. In this way, the phase
modulation for every pixel and for every value of the entrance signal can be determined experimentally.
Additionally, data acquisition can be significantly simplified with this scheme [-]
