  • Publication number: 20100014081
    Abstract: A Spectrometer is provided including a camera and an axial symmetric camera mount configured to receive the camera and to rotate. The spectrometer furthers include an input for providing optical radiation to a spectrometer system; a diffraction grating for dispersing the optical radiation along a prescribed plane; at least one lens for focusing wavelength-dispersed light onto at least one array of a detector of optical radiation, wherein the camera has at least one linear array of elements for detecting optical radiation; a mechanical housing, wherein the axial symmetric camera mount is configured to couple the camera to the mechanical housing; and a means for rotating the camera coupled to the mechanical housing about an axis. Related systems and methods are also provided.

  • Publication number: 20090268161
    Abstract: OCT imaging systems are provided for imaging a spherical-type eye including a source having an associated source arm path and a reference arm having an associated reference arm path coupled to the source path. The reference arm path has an associated reference arm path length. A sample is also provided having an associated sample arm path coupled to the source arm and reference arm paths. A lens having a focal power optimized for a diameter of the spherical-type eye is provided along with a reference arm path length adjustment module coupled to the reference arm. The reference arm path length adjustment module is configured to automatically adjust the reference arm path length such that the reference arm path length is based on an eye diameter of the subject.

  • Publication number: 20090141237
    Abstract: A system for imaging a sample is provided that includes an optical coherence tomography (OCT) portion having an associated OCT path. A second imaging portion is provided having an associated second image path, different from the OCT path. A fixation target having an associated fixation path, different from the second image path and the OCT path is also provided. The OCT path, the second image path and the fixation path are confocal at a common image plane. Related handheld systems are also provided.

  • Patent number: 7280196
    Abstract: A spectrophotometric system includes a zoom lens assembly that is mounted for axial translation relative to an integrating sphere. The zoom lens assembly includes first and second focusing lens mounted to an axially movable lens carrier. The lens carrier is positioned intermediate first and second sets of mirrors for reflecting/directing SCE and SCI beams toward fiber ports. A reference beam is also emitted from the integrating sphere and transmitted to a processor, thereby resulting in simultaneous tri-beam measurements. The disclosed spectrophotometric systems may also include an aperture plate detection assembly and/or a sample holder assembly that incorporates a dampening gas spring. The aperture plate detection system includes a detection disk that may include a plurality of pre-positioned sensors that interact with an activating ridge formed on the aperture plate for identification thereof.

  • Patent number: 5410739
    Abstract: An apparatus that causes variable data messages to be transmitted automatically following transmission of voice signals over a given communication channel. The apparatus includes a microprocessor for processing variable data to generate a variable data message, and is adapted to be coupled between a radio interface circuit and a microphone handset having a momentary push-to-talk switch in such a manner so as to be transparent during transmission of voice signals while the momentary PTT switch is being actuated. The microprocessor detects deactuation of the PTT switch and responds thereto by providing the variable data message to the radio for transmission. A GPS navigational computer and receiver processes received variable GPS position data to determine the position of the vehicle in which the apparatus is located, and generates a variable position data message component.
