Abstract: A grazing-incidence interferometer includes first and second spaced-apart diffractive optical elements with a generally planar object disposed therebetween. The first diffractive optical element forms sheared first-diffracted-order light beams that reflect from opposite first and second surfaces of the object at grazing-incidence angles, while a zero-diffracted-order light beam goes unreflected. The second diffractive optical element combines the unreflected zero-diffracted-order light beam and the sheared reflected beams to form a collimated, combined beam. A 1× double-telecentric relay system relays the combined beam to a folding optical system that forms first and second interference images on a diffusing screen located at an image plane. Digital images of the first and second interference images are obtained and processed to characterize the thickness variation of the object.

Abstract: A low-coherence Fizeau interferometer includes a first beamsplitter, a test arm and a reference arm, the first beamsplitter splits light into a first portion of light directed to the test arm and a second portion of light directed to the reference arm, and an imaging arm comprising a first collimating lens, a flat reference surface, and a test element. The test arm focuses the first portion of light at a first focal point, such that a virtual image of the first focal point appears at a focal point of the test element. The reference arm focuses the second portion of light at a second focal point, the first collimating lens collimates the light that then reflects off the flat reference surface. The second beamsplitter directs the first portion of light to reflect off the test element. The reflection of the first and second portion of light form an interference pattern.

Abstract: A display apparatus has an image generator that generates image-bearing light from a surface and a lens spaced apart from the image generator and having an aspheric incident refractive surface concave to the image generator and having an aspheric reflective surface concave to the image generator, wherein a principal axis of the reflective surface is normal to the image generator. A beam splitter plate disposed in free space between the image generator and the lens has first and second parallel surfaces that are oblique to a line of sight of a viewer. The lens and the beam splitter plate define a viewer eye box for the image-bearing light along the line of sight of the viewer.

Abstract: A light multiplexing system includes a color combining element and first, second, and third color channels. Each color channel includes a light source that directs light of a corresponding first, second, or third wavelength band, respectively, toward the color combining element. The color combining element includes first and second windows. The first and second windows are made of a solid transparent material and include, collectively, three coated surfaces. The surfaces may be non-contiguous. A first coated surface receives light of the first, second and third wavelength bands. The first coated surface reflects the light of the first wavelength band and transmits the light of the second and third wavelength bands. A second coated surface receives light of the second and third wavelength bands transmitted by the first coated surface. The second coated surface reflects the light of second wavelength band and transmits the light of the third wavelength band. The third coated surface receives the light of the third wavelength band transmitted by the second coated surface and reflects it. The reflected first, second, and third wavelength bands exit the first surface of the color combining element as a coaxial beam.

Abstract: An optical imaging system for cell culture monitoring is provided. The system includes an illumination segment having an illumination source and a collimating lens positioned between a first surface of a cell culture vessel and the illumination source. The illumination source and the collimating lens are arranged to transmit light through the first surface at an angle oblique to the first surface of the cell culture vessel. The system also includes a detection segment having a detector and a lens positioned between the first surface of the cell culture vessel and the detector. The lens focuses light to the detector through an aperture stop, and the detector receives light that exits the first surface of the cell culture vessel at an angle oblique to the first surface.
