Software Configurable Optical Test System (SCOTS)[1], a computerized "reverse Hartmann test", can rapidly quantitatively measure highly aspherical shapes such as solar collectors, Giant Magellan Telescope (GMT) primary segment with accuracy to micron rms or better without complex calibration. Implementation of SCOTS needs only hardware like a laptop computer. It illuminates test surface/system with patterns from a LCD screen and use reflected/refracted image to determine surface/system wavefront slope variations.
