Figure 8 : Adaptive holographic interferometer based on a single
mode reference optical path and a multimode signal path. A
piezoelectric transducer enables to apply a phase modulation on
the signal arm. HH’ : free space optics for controlling the beam
sizes; D : diaphragm; BS : beam splitter; PC: polarizationcontroller; OASLM : optically addressed spatial light modulator;
L : lens for far field
