Abstract:
According to the conventional light detection of a light probe microscope, there have been a problem that an excessive stray light is detected in case that a detector whose light-intercepting face is large with respect to the size of a bright point is used, and a problem that an optical axis alignment is necessary in case that the detector having a small light-intercepting face in the order of the bright point is used. Besides, in order to obtain plural optical information, plural light detectors have been necessary. It is adapted such that, by using a two-dimensional image sensor, a two-dimensional image is obtained in real time, and a signal intensity of an optional detection region in the two-dimensional image is obtained by picture signal processing means. It is adapted such that plural information are image-formed on the two-dimensional image sensor, and plural detection regions are designated.
Abstract:
An infrared LASER diode based high intensity light (100) for use as an aircraft landing light or searchlight in conjunction with night vision imaging systems. The high intensity light (100) uses infrared LASER diodes (110) installed into a heat sink (112) for temperature stability. The infrared light emitted from the LASER diodes (110) is transmitted to an optical positioning plate (106) by optical transmission means (108). The optical positioning plate (106) combines the emissions of the individual LASER diodes (110) to a single infrared light beam, which is collimated by an aspheric lens (102).

A stage positioning system including a stationary frame, a slide movable relative to the frame in a first direction, and a support platform connected to the slide and movable therewith in the first direction. The support platform is movably attached to the slide for movement in a second direction generally orthogonal to the first direction. The system will further include a first linear motor containing a first magnet assembly and a first coil device that engages the first magnet assembly to move the slide in the first direction. A second linear will contain a second magnet assembly and a second coil device that engages the second magnet assembly to move the support platform in the second direction. The stage positioning system is particularly suited for positioning an article in electron beam or EUV light lithography systems.

The light source device includes a plurality of laser diodes, a temperature sensor provided in the vicinity of the plurality of laser diodes, a control loop for controlling the temperatures of the plurality of laser diodes according to an output from the temperature sensor to thereby control the oscillation wavelengths of the plurality of laser diodes, and a unit for compensating temperature control conditions for the laser diodes other than a reference laser diode selected from the plurality of laser diodes, according to a change in temperature control condition for the reference laser diode. By the compensation of the temperature control conditions, the oscillation wavelength of each laser diode can be easily stabilized to each wavelength channel of WDM.

Abstract:
Since a notification unit (130) notifies a radiographer of the driving state of an X-ray detector (110), he/she can identify that the X-ray detector (110) is set in a detection signal accumulation state. When the irradiation button of an X-ray generation apparatus is then pressed, a subject can be irradiated with X-rays.
Abstract:
Method, components, design and fabrication process of a advanced X-ray flat panel detector (FPD), with built-in anti-scattering grid to reduce the X-ray scattering are disclosed. We further disclose two methods in the new X-ray detector: In the first method, the grid is placed on top of X-ray scintillator layer of a FPD, the pixels of X-ray FPD underneath are aligned with the hole structures of anti-scatter grids. The high performance anti-scatter grid applied and aligned to the flat panel detector (FPD) pixel-by-pixel can significantly reduce the noise from the scattered X-rays. The key advantages of the improved art are substantial reduction of grid shadow, improved image contrast-to-noise ratio (CNR) and minimized attenuation of direct X-rays. The new FPD with built-in grid may significantly enhance X-ray imaging system performance for a FPD based digital detection system with high image quality, high throughput and low cost for many X-ray imaging applications. In the second method, the grid may be fully or partially filled with X-ray scintillators and the combined sensor plate can be applied as X-ray sensor on a FPD. This plate integrates X-ray scintillator with anti-scatter grid. Using this scintillator plate on FPD, the key X-ray detector performances, such as image contrast-to-noise ratio (CNR), modulation transfer function (MTF), and detective quantum efficiency (DQE) may be improved significantly. The design of the detector plate allows flexible choices of the various scintillators to meet specific requirements of an X-ray imaging system, without sacrificing the detector performances such as the scattering X-ray rejection and MTF.
