摘要:
A system and methods for detecting particles and soluble chemical entities in body fluids consists of a system consisting of a microscopic apparatus, a sample chamber and reagents and methods used to detect, classify and enumerate particles and chemical entities in body fluids. Body fluids containing particles combined with reagents sediment to the bottom of a viewing chamber bringing them into the focal place of a digital microscopic detector. Particles identified as areas within a captured digital image that absorb or emit electromagnetic radiation can be further classified based on additional absorbed or emitted electromagnetic radiation within the predefined areas of the first digital image. Soluble chemical entities in body fluids are detected and concentrations determined using transmitted or emitted electromagnetic radiation using known chemical or antibody reactions, making the microscopic device a general purpose detector for in vitro determinations using body fluids.

A microscope apparatus includes a light source configured to emit a coherent illuminating light, an optical system configured to irradiate a specimen with the illumination light, and a detector configured to form an image based on a light generated from the specimen by the illumination light that irradiates the specimen. The optical system is configured to project a plurality of focal points of the illumination light on the specimen, and allow the plurality of focal points to interfere with each other while changing phases of the plurality of focal points.

Provided is a microscope that allows irradiation with uniform illumination light without decreasing the amount of light. Employed is a microscope 1 including an incoherent light source 31 that emits incoherent light I; an optical fiber 35 on which the incoherent light I is incident and which guides the incident incoherent light I by repeated total reflection; a DMD 37 having an array of movable micromirrors each reflecting or transmitting the guided incoherent light I; an objective lens 18 that irradiates a specimen 19 with the incoherent light I reflected or transmitted by the DMD 37 and that collects fluorescence F coming from the specimen 19; a dichroic mirror 17 that splits off the collected fluorescence F coming from the specimen 19 from the incoherent light I; and a CCD camera 13 that is disposed at a position conjugate to the position of the DMD 37 and that detects the fluorescence F coming from the specimen 19 and split off by the dichroic mirror 17.

A digital interface interconnected between a controller for a spatial light modulator device and a pattern generation subsystem. The digital interface comprises a clock which provides a clock signal and a logic device responsive to pattern image data output by the pattern generation subsystem and the clock signal and configured to assign pixels to the pattern Image data and to serialize the assigned pixels according to the clock signal to reformat the pattern image data to correspond to the spatial addressing of the spatial light modulator device.

摘要:
An apparatus and method allowing an optimized illumination in a light profile microscope by excitation of a sample with an elliptically collimated beam. The beam, which is typically supplied by a laser, is collimated with unequal beam waist radii (and Rayleigh ranges) along major and minor axes orthogonal to a propagation direction, and approximates a plane sheet of illumination. The plane sheet of illumination is aligned with a thinnest width dimension thereof along the optic axis of the microscope objective, and with a center thereof at the object plane of the objective. Excitation light in a test sample is thereby confined to within a narrow thickness of the object plane of the objective lens, which minimizes out-of-focus light in the image. The major axis width of the plane illumination sheet is typically a factor of ten or more greater than the minimum width, allowing a large area of the test sample to be illuminated and imaged. This excitation arrangement optically emulates the operation of micro-toming a thin cross section of a material for analysis, and provides optimum resolution and field in a light profile microscope.
