title = "Static metrology of the meter-scale deformable heliostat",
abstract = "This paper describes a heliostat metrology system which is developed based on deflectometry, utilizing a static perforated panel instead of conventional dynamic monitor displays to provide incident rays. The developed method is named static screen deflectometry (SSD). This robust and scalable method is especially valuable for outdoor tests of large reflectors used in concentrating solar-thermal power (CSP) systems. The developed method has been successfully demonstrated on a 2.4 m × 3.3 m float glass deformable reflector bent to focus sunlight at 113 m distance throughout a day. From images obtained from a camera at 50m distance, the reflector surface was measured to an accuracy of less than 1 mrad rms slope error in the full test scope.",
