Abstract: A beam homogenizer that minimizes undesired intensity variations at the output plane caused by sharp breaks between facets in previous embodiments. The homogenizer includes a hologram made up of irregularly patterned diffractive fringes. An input beam illuminates at least part of the hologram. The hologram transmits a portion of the input beam onto an output plane. In doing so, the energy of the input beam is spatially redistributed at the output plane into a homogenized output beam having a preselected spatial energy distribution at the output plane. Thus, the illuminated portion of the output plane has a shape predetermined by the designer of the homogenizer.

Abstract: Mass production of integrated optical subsystems may be realized by providing a bonding material surround each die in an array of first dies on a wafer. A plurality of second dies are then aligned with the dies on the wafer. The bonding material is then treated to bond the aligned dies. The bonded dies are then diced to form a bonded pair of dies containing at least one optical element, thus forming an integrated optical subsystem. The bonding material may be provided over at least part of the optical path of each first die, over an entire surface of the wafer or around the perimeter of each first die. The second dies may be provided on another wafer. Either die may contain active elements, e.g., a laser or a detector. The optical elements may be formed in the die or may be of a different material than that of the die.

Abstract: An improved optical system is disclosed for projecting light in the form of an image to a remote target. The laser light source and a holographic optical element are mounted together in optical alignment. The optical element is created using iterative discrete computer encoding for optimum efficiency. In alternate embodiments, the diffractive optical element has a collimating lens encoded into the grating levels and it also performs soft aperture circularizing using either amplitude or phase control over the coherent light. An embossed diffractive optical element laminated to an injection-molded refractive element is also disclosed.

Abstract: A spectrometer for use with a desired wavelength range includes an array of filters. Each filter outputs at least two non-contiguous wavelength peaks within the desired wavelength range. The array of filters is spectrally diverse over the desired wavelength range, and each filter in the array of filters outputs a spectrum of a first resolution. An array of detectors has a detector for receiving an output of a corresponding filter. A processor receives signals from each detector, and outputs a reconstructed spectrum having a second resolution, the second resolution being higher than any of the first resolution of each filter. Filters and detectors may be arranged into a plurality of imaging units, each imaging unit including first and second filters and first and second photosensing regions. A processor receives signals from each imaging unit, and generates a reconstructed spatial image comprised of discrete spatial units corresponding to each imaging unit.
