International Classification:

G02B 5/18

US Classification:

359566, 359900, 385 37, 385147

Abstract:

A method of manufacturing optical identification elements that includes forming a diffraction grating in a fiber substrate along a longitudinal axis of the substrate. The grating includes a resultant refractive index variation. The method also includes cutting the substrate transversely to form a plurality of optical identification elements that have the grating therein along substantially the entire length of the elements. Each of the elements has substantially the same resultant refractive index variation.

International Classification:

G01N 33/552

US Classification:

436521, 436501

Abstract:

A method and apparatus are provided for aligning optical elements or microbeads, wherein each microbead has an elongated body with a code embedded therein along a longitudinal axis thereof to be read by a code reading device. The microbeads are aligned with a positioning device so the longitudinal axis of the microbeads is positioned in a fixed orientation relative to the code reading device. The microbeads are typically cylindrically shaped glass beads between 25 and 250 microns (μm) in diameter and between 100 and 500 μm long, and have a holographic code embedded in the central region of the bead, which is used to identify it from the rest of the beads in a batch of beads with many different chemical probes. A cross reference is used to determine which probe is attached to which bead, thus allowing the researcher to correlate the chemical content on each bead with the measured fluorescence signal. Because the code consists of a diffraction grating typically disposed along an axis, there is a particular alignment required between the incident readout laser beam and the readout detector in two of the three rotational axes.

US Classification:

359298, 359290, 359630

Abstract:

A method and system for reducing speckle in an image produced from a coherent source of radiation is provided. The method includes coupling a source beam received from a coherent optical source into an optical fiber. A position of at least a portion of the fiber may be modulated using a ditherer. The source beam may be refracted by a lens after it is decoupled from the optical fiber, such that the source beam is aimed at a microlens diffuser. In accordance with a particular embodiment, the source beam may be projected from the microlens diffuser onto a spatial modulator. The spatial modulator may be positioned to project the source beam via an imaging lens, to a target.

International Classification:

G02B005/18

US Classification:

359/566000, 359/002000

Abstract:

A method for manufacturing a diffusion grating-based optical identification element is provided. The optical identification element includes a known optical substrate, having an optical diffraction grating disposed in the volume of the substrate. A large number of substrates or microbeads having unique identification codes can be manufactured winding a substrate, such as a fiber, around a polygonal shaped cage/basket to form a fiber ribbon having flat sections. A grating writing station writes one or more gratings into each flat section to form a unique code to this section. Each flat section of fibers of the fiber ribbon is written with the same gratings to provide the same identification code, or alternatively each flat section may be have a different grating(s) written therein so that each section has a different identification code. The fiber ribbon is then removed from the cage and diced to form a groups of optical identification elements, each group having unique optical identification codes.

G01B 9/02

Abstract:

An Optical Coherence Tomography receiver may include prisms, polarizing beam splitters, reflectors, lenses, and a photodetector array arranged in a compact package. Sample and reference beams are combined into an interference beam and split in two. The two resulting interference beams are then split into two polarization sates each. The optical path lengths for both pairs of interference beams with the same polarization state are equal or nearly equal.

A cross reference is used to determine which probe is attached to which bead, thus allowing the researcher to correlate the chemical content on each bead with the measured fluorescence signal. Because the code consists of a diffraction grating typically disposed along an axis, there is a particular alignment required between the incident readout laser beam and the readout detector in two of the three rotational axes. The third axis, rotation about the center axis of the cylinder, is azimuthally symmetric and therefore does not require alignment.
