  • Patent number: 7002688
    Abstract: A diagnostics apparatus for detecting fluorescence events related to the presence of an analyte in a sample is disclosed. The apparatus includes a housing, a source of excitation light and a photodetector, and a unitary multi-surface optical module. The optical module is integrally formed and composed of an upstream portion having a focusing optical surface for directing excitation light from the light source to a focal region within an analyte-detection zone in the apparatus, and a downstream portion having a second focusing powered optical surface and at least one reflecting surface for directing fluorescence-emission light produced by fluorescence events within the detection zone, in a direction substantially normal to the path of the excitation light onto the photodetector. The optical module is adaptable to a variety of assay formats, including multiple-sample, sample-array, and disposable-cartridge formats.

  • Patent number: 5835133
    Abstract: A mechanism and method for recording stereo video with standard camera system electronics and a uniquely adapted optical assembly is disclosed. The optical assembly comprises left and right optical channels disposed to capture and project separate left and right images onto a single image sensor such that the boundary between the projected images is sharply delineated with no substantial overlap or gap. The viewpoints of the left and right optical channels are separated by a distance, d, such that the captured images are differentiated to produce a stereo image pair. By proper disposition of the left and right optical channels, stereo image pairs exhibiting full stereo overlap without keystone distortion are obtained. One image of the stereo pair is produced for visualization by the left eye and the other image is produced for visualization by the right eye. Alternatively, the images can be interrogated by a computer system for generating three dimensional position data.

  • Patent number: 5801849
    Abstract: The document scanner of the present invention includes a reading assembly of simple, compact and light-weight construction. The reading assembly includes an optical system having a relatively short focal length. The reading assembly is thus simply configured in a compact manner close to the document to be scanned. The optical system is also configured to extend in a particular direction beyond the document viewing area for improved resolution of images from a bound document adjacent the binding. The reading assembly further includes a compact and light-weight illumination source which is low in power consumption, and thus, may be powered by batteries. The stand-alone document scanner of the present invention is particularly suited to portability.

  • Patent number: 5742113
    Abstract: A device for the tilt-free movement of one solid body with respect to a reference body is achieved by fixing first and second plates, illustratively with large central apertures, in spaced-apart parallel planes with cylindrical flexure tubes sandwich therebetween. Each of the flexure tubes includes an upstanding piezoelectric or electro-strictive cylinder therewithin. The flexure tubes are aligned radially from the common central axis of the plates and are conveniently at 120 degree angles with respect to one another to achieve symmetry. The piezoelectric cylinders are responsive to like voltage signals to expand or contract in a manner to expand or contract the diameter of the flexure tube to produce the desired tilt-free movement of one plate with respect to the other. The flexure tubes, although small, are very strong due to the cylindrical geometry and yet, are responsive to relatively low signal levels for producing the requisite expansion and contraction.

  • Patent number: 5629801
    Abstract: A reflective/diffractive light valve system collects light from multiple dimensions around a single light source. From these multiple collection dimensions, the light is directed to impinge on the valve from multiple directions. When the valve is configured to be reflective, the light returns to the source. On the other hand, when the valve is configured to be diffractive, light from a first and third order diffraction are transmitted from the valve for each of the collection dimensions which greatly enhances the efficiency of the system.

  • Patent number: 5085506
    Abstract: An image projection apparatus in which an image object plane contains a plurality of reflecting images and a light source and optical system projects a beam on each of said plurality of images. Spaced projection lenses are positioned to receive the light reflected from the images and direct the light on a projection surface with the plurality of reflected images in coregistration.

  • Patent number: 5083854
    Abstract: A spatial light modulator is disclosed with a first lens array disposed adjacent to a matrix of light modulators, and in proximity to a liquid crystal light valve containing a photoconductive element. Low intensity light is collimated by a lens element to illuminate an optical aperture which has geometric configuration similar to that of the matrix element. The first lens array focuses light from the illuminated aperture into the pupil of a matrix addressed spatial light modulator element. The second lens array collects light emitting from the light modulator element, and focuses the image of the aperture onto the photoconductive element of the liquid crystal light valve so as to preserve the geometrical and positional configuration of the optical aperture, and magnify the size of the illuminated region on the photoconductor. The design of the optics is such that when adjacent apertures are imaged onto the photoconductor, the proximate boundaries of the illuminated regions are contiguous.

  • Patent number: 4775788
    Abstract: The position and motion of a rotating element is determined by using a two-grating moire pattern. Movement of the element causes a projected scale image representing radiation reflected from the element to shift relative to a fixed grating thereby generating moire fringes. The accumulated fringes serve to measure absolute position and motion of the element.

  • Patent number: 4705996
    Abstract: The position of a rotating element is controlled by a galvanometer and a servo system. The position of the rotating element is determined by using a two-grating moire pattern. Movement of the element causes a projected scale image representing radiation reflected from the element to shift relative to a fixed grating thereby generating moire fringes. The accumulated fringes serve to measure absolute position and motion of the element. The servo digitally processes the measured position to generate several force components which are then combined to control the amount of force applied by the galvanometer to rotate the element.
