Paper Abstract

At present, two wavefront sensor concepts are being developed which drive the deformable mirror in real-time phase conjugate adaptive optical systems. Analyses show that the Hartmann-type sensor and the shearing interferometer can both approach optimum theoretical performance, and, in fact, shearing interferometer sensors have been built which demonstrate this capability. Until now, however, the optimum Hartmann-type sensor has not been built because proposed implementations do not take advantage of AC detection required for long wave application, and because the simple Hartmann sensor poses severe engineering problems of system alignment. The Integrated Imaging Irradiance (I3) Sensor (U.S.Patent #4,141,652) incorporates several novel features which overcome these difficulties, resulting in an AC Hartmann-type sensor that has demonstrated optimum performance with relaxed engineering requirements.
