ABSTRACT:
The invention relates to a device for recording a matrix of holographic lenses such that each lens, upon illumination by a monochromatic parallel beam produces a diffracted beam passing by a same common fixed aperture, which may be the pupil of a lens. In this device, an appropriate two-dimensional diffraction grating creates as many diffracted beams as there are lenses to be recorded, which beams interfer with a single parallel beam at the level of a photosensitive substrate. It is thus possible to carry out simultaneous recording of all the lenses of the matrix, which can afterwards be used in the recording of storage planes for optical stores.
