Abstract:
An optical measuring device comprises a plane mirror (3) having a center opening part functioning as a light entrance window or a light source mounting part (5) and an observation window (6') enabling the measurement by a light detector (6) and an integrating hemisphere (2) having the center of the radius of curvature in the center opening part of the plane mirror (3) and of which the inner wall surface functions as a light diverging and reflecting surface (1). An integrating space is formed between the plane mirror (3) and the integrating hemisphere (2). ® KIPO & WIPO 2009
Abstract:
PURPOSE: A mobile terminal is provided to minimize a dark area of an aperture of a window layer formed in a part corresponding to a front optical sensor, as not degrading the function of the optical sensor. CONSTITUTION: A glass (210) comprises a transparent material. The glass covers a through-window of a case. The glass is located on the upper part of an optical sensor. A window layer (220) is laminated on the inner side of the glass. The window layer has a fine hole. The fine hole is formed on the upper part of the optical sensor.
Abstract:
A system in one embodiment includes a source for directing a beam of radiation at a sample; a multilayer mirror having a face oriented at an angle of less than 90 degrees from an axis of the beam from the source, the mirror reflecting at least a portion of the radiation after the beam encounters a sample; and a pixellated detector for detecting radiation reflected by the mirror. A method in a further embodiment includes directing a beam of radiation at a sample; reflecting at least some of the radiation diffracted by the sample; not reflecting at least a majority of the radiation that is not diffracted by the sample; and detecting at least some of the reflected radiation. A method in yet another embodiment includes directing a beam of radiation at a sample; reflecting at least some of the radiation diffracted by the sample using a multilayer mirror; and detecting at least some of the reflected radiation.
Abstract:
There is provided a laser energy measuring unit whose laser energy measuring range is widened. The laser energy measuring unit has a filter provided within an optical path of laser to attenuate energy of the laser, a calculating section for measuring the energy of the laser passing through the filter and a condenser lens provided on one side of the filter for condensing the laser. The filter has a shading portion for blocking a center part of the laser beam from transmitting through the filter at position coincident with the center of the laser. The center part of the laser where its energy is large is cut by the shading portion and the calculating section measures the part where its energy is not so large. Thereby, it is possible to widen the laser energy measuring range.
Abstract:
In one embodiment, apparatus is provided with a light source, an optic element, at least one photosensor, and a control system. The optic element has a reflective material on a surface thereof, and is positioned to receive and reflect light emitted by the light source. The at least one photosensor is mounted to the surface of the optic element on which the reflective material resides, over a portion of the optic element on which the reflective material does not reside. The control system is operably associated with both the photosensor(s) and the light source, to regulate the light source's light output in accordance with measurements received from the photosensor(s).
Abstract:
A method and apparatus for braking an AC motor in the higher portion of its speed range includes substantially reducing flux before applying reverse torque commands to brake the motor. A DC link bus regulator is employed to prevent increases in bus voltage and frequency.
