An imaging device (500) comprises: a first telecentric system (SYS1) to form a first image (IMG1) of an object (OBJ1),5 a second telecentric system (SYS2) to provide a bundle of output beams (LB5a,LB5b) for forming a second image (IMG2) such that the output beams (LB5a,LB5b) are formed from light received from the first image (IMG1), and a first dispersive element (G1) positioned between the first telecentric system (SYS1) and the second telecentric system (SYS2) to provide a bundle of deflected light beams (LB3a,LB3b) such that the direction of the deflected light beams (LB3a,LB3b) depends on the wavelength (κ), wherein the second telecentric system (SYS2) is arranged to form the output beams (LB5a,LB5b) from light of the deflected light beams (LB3a,LB3b), and the second telecentric system (SYS2) comprises an aperture stop (AP2) to reject light which is outside a selected spectral range (PB1).
Abstract:
A system (100) and method for spectroscopic mapping, with configurable spatial resolution, of an object include a fiber optic bundle (112) having a plurality of optical fibers arranged in a first array (110) at an input end with each of the plurality of optical fibers spaced one from another and arranged in at least one linear array (114) at an output end. A first mask (108) defining a plurality of apertures equal to or greater in number than the plurality of optical fibers is positioned between an object to be imaged and the input end of the fiber optic bundle. An imaging spectrometer (102) is positioned to receive light from the output end of the fiber optic bundle and to generate spectra of the object. A sensor (118) associated with the imaging spectrometer converts the spectra to electrical output signals for processing by an associated computer.

Die Dielektrizitätsschicht (103) weist eine Dicke auf, die kleiner als die oder gleich der Hälfte einer vorgebbaren unteren Grenzwellenlänge ist, welche kleiner als die obere Grenzwellenlänge ist.
Abstract:
A device (300, 400) for determining gas concentration of a volume (301 ) in a closed space non-invasively, comprises a laser emitting means (302) for emitting laser beam (306) into said volume (301 ) in order to produce rotational Raman scattering of at least one gas component to be determined within said volume (301 ). A first guiding means (309) is used for guiding scattered beams (307) from the volume (301 ) to a filter (305), which transmits essentially only bandwidth of the scattered beams (307) and not the bandwidth of the laser (302). A detector (311) is used for detecting intensities of the scattered beams (307). In addition a second guiding means (308) is used before the detector (311) for guiding and spreading the scattered beams (307) onto the surface of said detector (311) so that different wavelengths of scattered beams (307) are guided onto different locations on the surface of said detector (311), where each of said different wavelengths correspond to a certain gas component of the volume (301) detected.

Abstract:
An apparatus consisting of stacked slab waveguides whose outputs are vertically staggered is disclosed. At the input to the stacked waveguides, the entrances to each slab lie in approximately the same vertical plane. A spot which is imaged onto the input will be transformed approximately to a set of staggered rectangles at the output, without substantial loss in brightness, which staggered rectangles can serve as a convenient input to a spectroscopic apparatus. A slit mask can be added to spatially filter the outputs so as to present the desired transverse width in the plane of the spectroscopic apparatus parallel to its dispersion.
Abstract:
A system for performing high-speed, high-resolution imaging cytometry utilizes a line-scan sensor. A cell to be characterized is transported past a scan region. An optical system focuses an image of a portion of the scan region onto at least one linear light sensor, and repeated readings of light falling on the sensor are taken while a cell is transported though the scan region. The system may image cells directly, or may excite fluorescence in the cells and image the resulting light emitted from the cell by fluorescence. The system may provide a narrow band of illumination at the scan region. The system may include various filters and imaging optics that enable simultaneous multicolor fluorescence imaging cytometry. Multiple linear sensors may be provided, and images gathered by the individual sensors may be combined to construct an image having improved signal-to-noise characteristics.
