摘要： A liquid lens includes a segmented electrode that allows the simultaneous application of different potentials across the lens's meniscus to obtain a predetermined aberration correction condition and to adjust focal length as necessary to conform to the topography of the object being scanned. The lens also includes a gas plenum interfacing with one of the liquids of the lens to allow for volume changes in the lens cell due to temperature variations. This combination of features produces a liquid-lens cell capable of maintaining substantially constant transverse magnification and diffraction-limited image quality over a useful range of focal length. As such, the lens is particularly suitable for incorporation in an array of micro-objectives used in a scanning microscope.

摘要： A multi-mode scanning imaging system. The system includes a plurality of sets of optical elements and a scanning mechanism. Each set is disposed with respect to a corresponding image plane and configured to image respective portions of an object. A scanning mechanism produces relative translation between the sets and the object so as to scan the object. Sets of image sensors corresponding to the sets of optical elements are adapted to capture image data representative of the respective portions of the object. A mode implementation system coordinates the image data according to one or more desired modes of operation of the imaging system.

摘要： In a scanning microscope, slides are fed automatically from a magazine to the imaging system. Each slide is labeled in some fashion with information for selecting the appropriate modality of operation of the scanner for that slide and the modality is implemented automatically. The information is preferably tied to and defined by a laboratory information system (LIS). For example, the instructions may regard the type of microscopy (i.e., trans- or epi-illumination), multi-spectral imaging with particular spectral bands combined with a particular set of z-positions, alternative filters, settings for the numerical aperture of the condenser, alternative detector operation for different resolutions, and alternative post-scan analyses of the data, as deemed optimal for the scan. The label may also contain the slide's identity, a pathologist's name, desired post-scan handling protocol, etc. The preferred array microscope to carry out the invention is also described.

摘要： An array microscope scans a slide in rapid sequence at different wavelengths to record multiple spectral images of the sample. Full spatial resolution of the image sensor is realized at each color because pixels are not shared between spectral bands. The object and detector are placed at conjugate distances selected to produce substantially equal magnification with minimum chromatic aberration at all wavelengths to ensure registration of all images. Spectral analysis is carried out by combining the images captured at each wavelength. The greater-than-RGB spectral resolution provided by the combination of images enables the isolation and display of the effects produced by the contemporaneous use of more than two stains on a tissue for improved pathological analysis.

摘要： An epi-illumination system for an array microscope. For Kohler illumination, illumination light sources are placed, actually or virtually, at the pupils of respective individual microscope elements of an array microscope. In one Kohler illumination embodiment, the light source is a point source comprising the tip of an optical fiber placed on the optical axis at the pupil of its corresponding microscope element. In another Kohler illumination embodiment, the illumination light is provided by a reflective boundary placed on the optical axis of a corresponding microscope element. For critical illumination the light sources are placed at locations conjugate with their respective object planes so as to image the light sources thereon. For dark-field illumination, the support material around a microscope element lens, which is used to support an array of lenses, is fashioned to form an illumination optical element so that light from an off-axis source is directed by the illumination element toward the object plane at an angle such that light will not be reflected into the field of view of the imaging system, but scattered or fluorescence light will be within that field of view. The illumination optical element may be refractive element, a Fresnel element, a reflective element, a diffractive element, or some combination of one or more of these elements. An array of pinhole apertures may be provided to operate the array microscope in a confocal mode. All of the embodiments may be used for epi-fluorescence microscopy.

摘要： An imaging system with an integrated source and detector array. A plurality of light detectors are arranged in a detector array and a plurality of light sources corresponding to detectors in the detector array are arranged in a source array in an epi-illumination system so that light radiated from a point on the object illuminated by a given source is detected by a corresponding detector. An optical system is disposed with respect to the source array and the detector array so as to illuminate an object with light from the source array and image the object on the detector array. Ordinarily, the sources and detectors are coplanar and, preferably, are fabricated or at least mounted on the same substrate. One or more sources in the source array may have a corresponding plurality of detectors, and one or more detectors in the detector array may have a corresponding plurality of sources. In one embodiment the Airy pattern of the point response of the optical system encompasses both a detector and its corresponding light sources. In another embodiment, the optical pathway is split by a diffractive element to produce conjugate points corresponding to light sources and their respective detectors. In a further embodiment, the pathway is split by a Wollaston prism. In yet another embodiment where the illumination and image light have different wavelengths, the pathway is split by dispersion. The system is particularly suited for fluorescence imaging, confocal microscopy and array microscopes.

摘要： An imaging apparatus consists of multiple miniaturized microscopes arranged into an array capable of simultaneously imaging respective portions of an object. A continuous linear translation approach is followed to scan the object and generate multiple image swaths of the object. In order to improve the quality of the composite image produced by concatenation of the image swaths, the performance of each microscope is normalized to the same base reference for each relevant optical-system property. Correction factors are developed through calibration to equalize the spectral response measured at each detector, to similarly balance the gains and offsets of the detector/light-source combinations associated with the various objectives, to correct for geometric misalignments between microscopes, and to correct optical and chromatic aberrations in each objective.
