Wavefront measurement by solving the irradiance transport equation for multifocal systems Quiroga Mellado, Juan Antonio Gómez Pedrero, José Antonio Martínez Antón, Juan Carlos A method for sensing wavefronts is presented. The method is based on the resolution of the irradiance transport equation, which relates the irradiance distribution and the shape of the wavefront of a light beam propagating along a given direction. The method presents no restrictions in the locations of the measurement planes and incorporates an improved procedure to geometrically correct the acquired images to take into account the effect of ray deflection in the propagation of the irradiance distributions. With the proposed technique, we measure the wavefront at the exit pupil of a progressive addition lens and find good agreement with an alternative deflectometric method. 2023-06-20T18:51:17Z 2023-06-20T18:51:17Z 2023-06-20T18:51:17Z 2001-12 journal article https://hdl.handle.net/20.500.14352/58783 0091-3286 10.1117/1.1418715 metadata only access Spie-Soc Photo-Optical Instrumentation Engineers
