Abstract: A computer-aided image correction method for images with at least spatially partially coherent light requiring only a phase-modulated image as input. It does not reconstruct the phases on the image sensor, but rather assumes that they should ideally all be the same. With this assumption, the invention formulates a constraint and an update rule. The result of the iteration is an amplitude distribution of the lightwave field, which could have been measured directly if aberrations in the form of wavefront distortions had not contributed to the actual image acquisition. Further, a device that can, using the image correction method, be used as an adaptive optic for imaging instruments.

Abstract: An aero-optical disturbance measurement system includes a mirror supported by a gimbal for receiving a light beam from a light emitting source, reflecting the light beam to a first periscope fold mirror and therefrom reflecting the light beam directly to a second periscope fold mirror. A first concave off-axis paraboloid mirror receives the light beam reflected from second periscope fold mirror and therefrom a first fold mirror receives the light beam reflected directly from first concave off-axis paraboloid mirror. A second fold mirror receives the light beam reflected directly from the first fold mirror. A second concave off-axis paraboloid mirror receives the light beam reflected directly from second fold mirror which reflects the light beam to a fast steering mirror. A fine tracker camera coupled to an embedded processer receives portion of light beam from fast steering mirror. Embedded processor controls movement of fast steering mirror and gimbal.

Abstract: When the optical system is illuminated with an illumination light flux emitted from one extant input image point, an interference image generated by superimposing an extant output light flux output from the optical system and a reference light flux coherent with the extant output light flux is imaged to acquire interference image data, and thus to acquire measured phase distribution, and this acquisition operation is applied to each extant input image point. Thus, each measured phase distribution is expanded by expanding functions μn(u, v) having coordinates (u, v) on a phase defining plane as a variable to be represented as a sum with coefficients Σn{Ajn·μn(u, v)}. When the optical system is illuminated with a virtual illumination light flux, a phase Ψ(u, v) of a virtual output light flux is determined by performing interpolation calculation based on coordinates of a virtual light emitting point.

Abstract: A wavefront analyser is modified to simply determine the differences in amplitude and tilt which can exist between the different regions of an initial wavefront (S0). To achieve this, interference between two waves only is produced from beams (F1, F2) which come from neighbouring regions on the initial wavefront. Such an analyser can be used to coherently combine laser radiation produced by different sources arranged in parallel. Another use is for the determination of the differences in height and inclination which exist between the neighbouring mirror segments of a Keck telescope.

Abstract: A relatively high-resolution image from a conventional camera can be computationally combined with a relatively low-resolution wavefront measurement from, for example, a Shack-Hartmann sensor in order to construct a relatively high-resolution light-field image.

Abstract: A method of measuring characteristics of a wavefront of an incident beam includes obtaining an interferogram associated with the incident beam passing through a transmission mask and Fourier transforming the interferogram to provide a frequency domain interferogram. The method also includes selecting a subset of harmonics from the frequency domain interferogram, individually inverse Fourier transforming each of the subset of harmonics to provide a set of spatial domain harmonics, and extracting a phase profile from each of the set of spatial domain harmonics. The method further includes removing phase discontinuities in the phase profile, rotating the phase profile, and reconstructing a phase front of the wavefront of the incident beam.
