Abstract:
A mammography device 1 is an apparatus for acquiring internal information of a breast B of an examinee A by radiating light to the breast B and detecting the diffused light, and includes a container 3 configured to surround the breast B and a plurality of optical fibers 11 attached to be directed inward in the container 3 and configured to perform radiation and detection of light. The container 3 has a base member 30 having an opening 30a, a plurality of annular members 40 continuously disposed to come in communication with the opening 30a, and a bottom member 50 disposed inside the annular member 40 spaced the farthest distance from the base member 30. The annular members 40 and the bottom member 50 are configured to relatively displace the adjacent annular member 40 on the side of the base member 30 or the base member 30 in a communication direction. Some of the plurality of optical fibers 11 is attached to the plurality of annular members 40.
Abstract:
Apparatus for detecting optical radiation emitted from an array of spots on an object. The apparatus includes a plurality of light guides having respective input ends and output ends, with the input ends ordered in a geometrical arrangement corresponding to the array of the spots. Relay optics collect and focus the optical radiation from the object onto the input ends such that each input end receives the optical radiation from a corresponding one of the spots. Multiple detectors and each coupled to receive the optical radiation from an output end of a respective one of the light guides.
Abstract:
An apparatus for detecting spectra in light emanating from chemical or biochemical reactions occurring in at least one reaction vessel (3) of a plurality of reaction vessels is disclosed. Each reaction vessel (3) has a receptacle portion having an emitting area from which light can emanate. The apparatus may include a masking element (5) having an array of apertures (6) through which light from each reaction vessel (3) can escape. A plurality of light waveguides (7) are arranged to guide light from the apertures (6) in the masking element (5) to a light detecting device (10) for detecting the spectra of light substantially simultaneously. One or more further light waveguides (31) may be provided for each reaction vessel (3) for directing excitation light from one or more excitation light sources (32, 33) to the reaction vessels (3).
Abstract:
An imaging device uses a fiber optic faceplate (FOF) with a compressive sampling algorithm for the fluorescent imaging of a sample over an large field-of- view without the need for any lenses or mechanical scanning. The imaging device includes a sample holder configured to hold a sample and a prism or hemispherical glass surface disposed adjacent the sample holder on a side opposite the lower surface of the sample holder. A light source is configured to illuminate the sample via the prism or the hemispherical surface, wherein substantially all of the light is subject to total internal reflection at the lower surface of the sample holder. The FOF is disposed adjacent to the lower surface of the sample holder, the fiber optic array having an input side and an output side. The device includes an imaging sensor array disposed adjacent to the output side of the fiber optic array.
Abstract:
Certain examples described herein are directed to optical devices and systems that include first and second optical elements. In some examples, the first optical element may be configured to pass light received from an excitation source, and the second optical element may be optically coupled to the first optical element and may be configured to reflect incident light from the first optical element back to the first optical element and configured to pass the light reflected from the first optical element. Methods using the devices and systems are also described.
Abstract:
Photovoltaic thin film quality control is obtained where the thin film is supported by a support and a section of the film is illuminated by a polychromatic illumination source. The source forms on the thin film a continuous illuminated line. Discrete sampled points located on the illuminated line are imaged onto a two dimensional optical switch. A concordance look-up-table between the coordinates of the above sampled points on the thin film and their coordinates on the two dimensional optical switch are generated. The spectral composition of the illumination reflected by the sampled points is determined and photovoltaic thin film parameters applicable to the quality control are derived from the spectral composition of reflected or transmitted by the photovoltaic thin film illumination.
Abstract:
A method of controlling a device for imaging the interior of turbid media is provided. The device comprises: a receiving portion (2) for receiving a turbid medium (1) tobe examined; at least one light source (6) optically connected to the receiving portion (2) for irradiating the interior of the receiving portion (2); and at least one detector (7) opticallyconnected to the receiving portion (2) for detecting light emanating from the interior ofthe receiving portion (2). The at least one light source (6) and the at least one detector (7) areoptically connected to the receivingportion (2) such that a plurality of differentsource- detector position combinationsare formedover a complete measurement. The different source-detector position combinations define different light paths through the receiving portion (2). The method comprises a fast-measurement step in which a reduced set of data corresponding to onlya part of the plurality of source-detector position combinations is generated for providing fast-information about the interior of the receiving portion (2).
