    摘要: The invention provides imaging apparatus and methods useful for obtaining a high resolution image of a sample at rapid scan rates. A rectangular detector array having a horizontal dimension that is longer than the vertical dimension can be used along with imaging optics positioned to direct a rectangular image of a portion of a sample to the rectangular detector array. A scanning device can be configured to scan the sample in a scan-axis dimension, wherein the vertical dimension for the rectangular detector array and the shorter of the two rectangular dimensions for the image are in the scan-axis dimension, and wherein the vertical dimension for the rectangular detector array is short enough to achieve confocality in a single axis.

    摘要: A host matrix—normally a binder such as cellulose acetate propionate in a solvent such as acetone—contains a radiation-polymerizable photopolymer—normally a monomer like dipentaerythritol pentaacrylate in combination with a crosslinker like 1-vinyl-2-pyrrolidinone, an initiator like N-phenyl glycine, and/or a photosensitizer like camphor quinine—that is initially uniformly doped with a stable dye—typically Rhodamine B and/or Bodipy Red—that photoinitiates photopolymerization. Upon selective exposure of certain regions of the matrix by radiation, most normally laser light radiation, the dye will initially migrate and redistribute itself to radiatively-exposed regions until, dye migration being substantially complete, photopolymerization will occur, locking the migrated dye in place at a relatively higher concentration at the selectively exposed regions. The dye therein stably located can be optically detected by, preferably, light-radiation-stimulated fluorescence. The medium thus serves as an optical memory, including of the volume type, that can be reliably permanently written quickly and inexpensively at high density.

    摘要: A line scanning arrangement for imaging microarrays includes a line illuminator that converts output from one or more lasers to a radiation line. The laser output passes through a single mode fiber and a module that converts the laser light to the radiation line. The line is confocally directed to sites on the microarray, and retrobeams returned from the sites are collected on an imaging detector. The microarray is moved in the imaging apparatus so as to progressively illuminate an array or matrix of sites for imaging.

    摘要: A temperature compensation mechanism and associated methodology to provide compensation for temperature-induced drifts in the peak transmission wavelength of a liquid crystal (LC)-based tunable optical filter stage. The filter-staged based methodology uses a simple, empirical mathematical relationship that represents thermal effects on a liquid crystal-based filter stage by taking into account a relationship among the LC material's actual temperature coefficient (of thermal expansion), the operating temperature variation, and wavelength drift attributable to the temperature variation. In one embodiment, a control channel based mechanism is used to provides appropriate temperature compensation to a liquid crystal-based tunable optical filter by accurately calculating LC driving voltage values needed for temperature compensation and then supplying the calculated drive voltage to drive various LC components in the filter.

    摘要: Small particles, for example 5 μm diameter microspheres or cells, within, and moving with, a fluid, normally water, that is flowing within microfluidic channels within a radiation-transparent substrate, typically molded PDMS clear plastic, are selectively manipulated, normally by being pushed with optical pressure forces, with laser light, preferably as arises from VCSELs operating in Laguerre-Gaussian mode, at branching junctions in the microfluidic channels so as to enter into selected downstream branches, thereby realizing particle switching and sorting, including in parallel. Transport of the small particles thus transpires by microfluidics while manipulation in the manner of optical tweezers arises either from pushing due to optical scattering force, or from pulling due to an attractive optical gradient force. Whether pushed or pulled, the particles within the flowing fluid may be optically sensed, and highly-parallel, low-cost, cell- and particle-analysis devices efficiently realized, including as integrated on bio-chips.

    摘要: This invention provides rotors and methods of precisely metering a sample fluid and mixing the sample with a reagent. The rotors have a metering tube of defined volume that fills until sample flow is stopped by surface tension of a meniscus at a capillarity port, while excess sample is stripped from the metering tube inlet by centripetal force of the spinning rotor. By spinning the rotor at a higher speed, a reagent can be forced from a reagent chamber to contact the meniscus, breaking the surface tension and allowing the metered sample to mix with the reagent.
