Freeform Surface Metrology with Deflectometry
Deflectometry is one of the potential techniques for freeform surface metrology. The display panel is either LCD, LED, or OLD and it displays a certain pattern onto the freeform surface. The cameras then record how the pattern is distorted on the surface and this is fed into a processing unit where it calculates the surface shape. This invention involves...
