Oblique Incidence Interferometer Using Holographic Optical Elements

Optical elements made by holographic technology are called Holographic Optical Elements (HOEs). HOEs have some advantages as conventional optical elements are not equipped and have been applied in various optical devices. We have applied HOEs, a pair of holographic gratings and a holographic lens, in an oblique incidence interferometer. In following lines we call it OII as Oblique Incidence Interferometer.
