The invention relates to methods to improve SLMs, in particular to reflecting micromechanical SLMs, for applications with simple system architecture, high precision, high power handling capability, high throughput, and / or high optical processing capability. Applications include optical data processing, image projection, lithography, image enhancement, holography, optical metrology, coherence and wavefront control, and adaptive optics. A particular aspect of the invention is the achromatization of diffractive SLMs so they can be used with multiple wavelengths sequentially, simultaneously or as a result of spectral broadening in very short pulses.

A processing for specifying a correspondence relationship of feature points between two sets of optical data can be highly precise and efficiently carried out. The correspondence relationship of the perpendicular edges is obtained based on the assumption that the object is a building, in the processing for integrating the three-dimensional model obtained from the point cloud position data and the three-dimensional model obtained from the stereophotographic image. In this case, one perpendicular edge is defined by the relative position relationship with the other perpendicular edge, and the correspondence relationship is high-precisely and rapidly searched.
