Abstract

In this paper the use of a blazed holographic grating extends the filed of view (FoV) of a thin camera system. A blazed grating is designed to shift the center of the object field 10° from the axis. The designed blazed grating provides 69% maximum diffraction efficiency (DE) in the primary order over a 15° FoV. High diffraction efficiency is maintained over a wavelength range from 457.8 to 632.9 nm. The holographic blazed grating is fabricated in photoresist on a 1.5 mm thick glass substrate, index matching with a prism. The prism helps to make an adequate profile of the blazed grating. Experimental results confirm that the center in the object field is successfully shifted by the blazed grating for the FoV extender. This technique can be used to increase the numerical aperture (NA) of various optical systems.
