Freeform Computer-Generated Hologram (CGH) Metrology Demo

A detailed how-to video for measuring a freeform mirror using a CGH (computer-generated hologram) from AOM. We explore the concept of a Metrology Platform, which provides a mount for a test optic that simulates the mechanics that the part was designed to be mounted to - which is a big advantage when testing an optic! See how mechanical and optical features interact with a CGH to make alignment quick and easy, and enable snapshot measurements of aspheres and freeforms.
