    摘要: An optical device has a first medium that produces more photons that exit the first medium than enter the first medium, such as a gain material. A second medium that produces light of a different wavelength than the wavelength of light incident thereon, such as a second harmonic generator. The optical device defines a cavity including the first medium and the second medium. An energy source provides energy to at least one of the first medium and the second medium so that light exits the cavity, the energy source is modified in a number of different manners such that the optical device has decreased noise output.

    摘要: A tiled Bragg grating (BG) includes a plurality of BGs that are paralleled and optically contacted to one another. Each BG includes an optically transparent substrate within a predetermined wavelength or wavelength range having a length dimension and a transverse dimension. The BGs have a grating period along their length dimension. The BGs have optical contact regions along edges in their transverse dimension where the BGs are optically contacted to one another.

    摘要: An automatic fingerprint system includes an optical sensor having a first light source that provides a collimated beam for interrogating a first sample surface, and a camera including a lens and a photodetector array having a camera field of view (FOVCAMERA) large enough to image the first sample surface. The camera is critical angle positioned relative to the first light source to receive specular reflection (glare) from the first sample surface to generate image data from the glare. The first light source and camera have substantially equal and opposite numerical apertures (NAs). A computer or processor that includes reference fingerprint templates receives a digitized form of the image data, and includes data processing software for (i) comparing the image data to reference fingerprint templates to determine whether the image data includes at least one fingerprint and (ii) for generating a fingerprint image if the fingerprint is determined to be present.

    摘要: This document relates to systems and method for latent fingerprint detection using specular reflection (glare). An exemplary system may include a light source alignment portion configured to align a light source at an illumination angle relative to a sample surface such that the light source illuminates a sample surface so that the surface produces specular reflection. The system may also include a specular reflection discriminator that directs the produced specular reflection to an optical detector aligned relative to said sample surface at an alignment angle that is substantially equal to an angle of reflection of the produced specular reflection. Preferably, the directed specular reflection does not saturate the optical detector; and the optical detector captures the specular reflection from the sample surface and generates image data using essentially only the specular reflection.
