  • Publication number: 20190310180
    Abstract: In some aspects, a flow cytometer system is provided that includes beam shaping optics positioned to manipulate a light beam and produce a resulting light beam that irradiates the core stream at the interrogation zone of the flow cell. The beam shaping optics include an acylindrical lens positioned to receive and focus light in a direction of a first axis orthogonal to a direction of light travel, and a cylindrical lens positioned to receive the light output from the acylindrical lens and to focus the light output from the acylindrical lens in a direction of a second axis orthogonal to the first axis and to the direction of light travel. The resulting light beam output has a flat-top shaped intensity profile along the first axis, and a Gaussian-shaped intensity profile along the second axis. Related methods of shaping a light beam at an interrogation zone of a flow cell are also provided.

  • Patent number: 8755866
    Abstract: A system and method for optical lymph node mapping. The system is useful for guiding sentinel lymph node biopsy surgeries. A contrast agent that includes a fluorescent dye is injected near the site of a malignancy. The contrast agent drains into the lymphatic system, collecting in a sentinel node or nodes. The system utilizes one or more low-power continuous-wave lasers or light-emitting diodes modulated with a digital code sequence to probe the tissue suspected of containing the sentinel node. When the light is incident near the sentinel node, it will excite fluorescence from the dye. A portion of the scattered fluorescent light is captured with one or more photo-detectors. A correlation of the photo-detector signal and the digital code sequence is calculated to produce an estimate of the distribution of flight times for photons traveling from a given source to a given detector.

  • Patent number: 7697192
    Abstract: A thin-film interference filter structure has a generally wavelength-dependent resonant response to incident optical energy in a predetermined range of wavelengths. The thin-film interference filter structure includes a thermally tunable layer having a thermally tunable optical characteristic such that a range of wavelength-dependent resonant optical responses of the thermally tunable layer are induced by a corresponding range of thermal conditions of the thermally tunable layer. The thin-film interference filter structure is configured to (1) receive a spatially varying pattern of thermal energy at the thermally tunable layer to impart a corresponding spatially varying pattern to the thermally tunable characteristic of the thermally tunable layer, and (2) receive the incident optical energy into the thermally tunable layer and output optical energy having spatial modulation corresponding to the spatially varying pattern of the thermally tunable characteristic.

  • Patent number: 7560703
    Abstract: A signal conduction channel having a first element that receives electrons at a first end from a vacuum environment, produces photons as the electrons are received, and propagates the photons along a length of the first element to a distal second end, and a second element that receives the photons from the second end of the first element, converts the photons to electrons, and multiplies the electrons, where no additional element is disposed between the second end of the first element and the second element, except optionally at least one of a photon-conductive epoxy, a lens, and an optical coupling plate that touches both the second end of the first element and the second element.

  • Patent number: 6961506
    Abstract: One aspect is a method for controllably attenuating the beam of light (108) coupled between incoming and outgoing optical fibers (106) by misaligning minor surfaces (116a, 116b) included of an optical switching module (100). Misalignment of the mirror surfaces (116a and 116b) causes only a portion of the beam of light (108) propagating along the incoming optical fiber (106), which is less than when the light beam deflectors' mirror surfaces (116) are precisely aligned, to propagate along the outgoing optical fiber (108). Thus, the optical switching module (100) controllably attenuates the beam of light (108) coupled between the incoming and the outgoing optical fibers (106). Another aspect is a variable-optical-attenuator (“VOA”) (212) that includes an optically reflective membrane (222) upon which the beam of light (108) impinges. Application of an electrostatic field between an adjacent electrode (228) and the membrane (222) deforms the membrane (222) thereby attenuating an impinging beam of light (108).

  • Patent number: 6850475
    Abstract: An optical data storage system utilizes optical fibers for transfer of information to and from storage media. The storage media includes magneto-optical storage disks. The optical fibers are single-mode polarization maintaining optical fibers. A single frequency laser diode provides a source of polarized light. Accordingly, a polarization state conveyed by the polarization maintaining optical fiber is accurately reproduced with reduced noise, as compared to use of a Fabry-Perot laser diode.

  • Patent number: 6847661
    Abstract: A tunable laser comprising a laser source for providing light with a wavelength along an optical path. A diffractive element is positioned in the optical path and spaced from the laser source for redirecting the light received from the laser source. A reflective element is positioned in the optical path and spaced from the diffractive element for receiving the light redirected by the diffractive element and for further redirecting the light back along the optical path to the reflective element. The diffractive element receives the light further redirected by the reflective element and returns the light along the optical path to the laser source. The optical path created by the laser source, the diffractive element and the reflective element causes the light to lase at the wavelength. At least one microactuator is coupled to one of the diffractive element and the reflective element for moving such element to select the wavelength of the light.
