SC1332: Computer Generated Holograms for Optical Testing

Computer Generated Holograms (CGHs) are diﬀractive components that generate any desired wavefront. CGHs have been trusted for decades for measuring extremely high precision, high value optics, such as the primary mirror segments of the James Webb Space Telescope. This course explains the operational principle of CGHs, presents an overview of CGH metrology applications, and provides guidelines for how to specify CGHs to test freeform optics and subassemblies. Practical details of CGH usage are shared, such as strategies for test optic alignment (particularly important for freeform surfaces), and CGH-speciﬁc data processing steps to ensure measurement accuracy.
