Holographic optical element

A holographic optical element (HOE) is an optical element (such as a lens, filter, beam splitter, or diffraction grating) that is produced using holographic imaging processes or principles.^[1] Dichromated gelatin and photoresists are among the holographic recording materials used in forming holographic optical elements.^[2]^[1]^{[note 1]}

Holographic optical elements are commonly used in optoelectronics applications such as laser diodes for optical disc drive heads.^[1] They have been used in atomic force microscopy (AFM) pickup heads,^[3] and were used in the HARLIE (Holographic Airborne Rotating Lidar Instrument Experiment) scanning atmospheric backscatter LIDAR system by NASA.^[4]

One use of a holographic optical element is in thin-profile combiner lenses for optical head-mounted displays.^[5] A reflective volume hologram is used to extract progressively a collimated image that was directed via total internal reflection in an optical waveguide. The spectral and angular Bragg selectivity of the reflective volume hologram makes it particularly well-suited for a combiner using such light sources as RGB LEDs, providing both good see-through quality and good quality of the projected image. This usage has been implemented in smart glasses by Konica Minolta and Sony.^[6]^[7]
