Wavefront-sensor tomography for measuring spatial coherence Řeháček, Jaroslav Hradil, Zdenek Stoklasa, Bohumil Motka, Libor Sánchez Soto, Luis Lorenzo © 2015 SPIE. This work is co-financed by the European Social Fund and the state budget of the Czech Republic, project No.CZ.1.07/2.3.00/30.0041 (POST-UP II), and supported by the Grant Agency of the Czech Republic, Grant No. 15-031945. Wavefront sensing is an advanced technology that enables the precise determination of the phase of a light field, a critical information for many applications, such as noncontact metrology, adaptive optics, and vision correction. Here, we reinterpret the operation of wavefront sensors as a simultaneous unsharp measurement of position and momentum. Utilizing quantum tomography techniques we report an experimental characterization and 3D imaging of a multimode laser light. 2023-06-19T14:59:13Z 2023-06-19T14:59:13Z 2015 journal article 0277-786X 10.1117/12.2188040 https://hdl.handle.net/20.500.14352/35046 http://dx.doi.org/10.1117/12.2188040 http://proceedings.spiedigitallibrary.org/ eng CZ.1.07/2.3.00/30.0041 15-031945 open access Society of Photo-optical Instrumentation Engineers (SPIE)
