Abstract:
This portable light source apparatus accommodates a deuterium lamp 10 in a lamp box 42 and, at the same time, in a housing 41 in order for the influence of temperature changes in the outside air to become very small. Namely, the deuterium lamp 10, which is susceptible to changes in temperature, is enveloped not only by the lamp box 42 but also by the housing 41, thereby being accommodated in a double shield structure. As a result, the temperature change of the housing 41, which is the most likely to be affected by the outside air, is harder to be transmitted to the deuterium lamp 10, whereby the latter can be utilized without taking account of the changes in weather during outdoor operations or influences of air conditioners and the like during indoor operations. Further, the deuterium lamp 10 can be inserted into and removed from the lamp box 42 from thereabove, so that operations of replacing the lamp 10 become easier even when the housing 41 is made compact, whereby the light source apparatus can be carried easier outdoors and in the field.
Abstract:
PROBLEM TO BE SOLVED: To generate EUV radiation of a high average output which permits time-multiplexing of radiation beams of a plurality of source modules 4 in a simple manner without overloading the source modules and without requiring extremely high rotational speeds of mechanical components. SOLUTION: The present invention relates to an arrangement and a method for generating EUV radiation of a high average output, preferably for the wavelength region of 13.5 nm for use in semiconductor lithography. According to the present invention, a plurality of identically constructed source modules, which are arranged around a common optical axis, are oriented to a rotatably mounted reflector arrangement which successively unites the beam bundles of the source modules along the optical axis. The reflector arrangement has a drive unit, by which a reflecting optical element is adjustable as required so as to be stopped temporarily in the angular positions that are determined for the source modules 4, and is oriented to the next source module 4" in the intervals between irradiations by means of control signals radiated by a radiation device.

Abstract:
PROBLEM TO BE SOLVED: To provide a fluorescence detector capable of protecting eyes of a user without serving as a dedicated equipment. SOLUTION: This detector is a hand-held type fluorescence detector including a hand-held type data processing system and a UV ray source connected thereto. The UV ray source illuminates an object of a scanning object with light having a UV illumination wavelength. A safety mechanism restrains the ray from the UV ray source from reaching the eyes of the human being located in the vicinity of the UV ray source, with intensity of damaging the eyes of the human being. The fluorescence detector detects fluorescence generated by the object in response to the illumination. The fluorescence detector utilizes a photodetector or an observer of the human being. The detector may be included in a cellular phone or a PDA. A safety mechanism using a baffle or total internal reflection is explained to protect the user. An interlock mechanism may be included further to prevent the UV ray source from being driven when no object exists. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
A quantum dot light emitting device includes a grating device which includes a grating region that has a particular grating interval, and a quantum dot layer located above the grating region. The device provides high-purity color light based on a selection of a wavelength band by the grating region in correspondence with a wavelength band of light emitted from the quantum dot layer.
Abstract:
Systems and methods may provide for receiving an electrical measurement signal from a first photodetector coupled to a first waveguide and determining a total intensity level of reflected light in the first waveguide based on the electrical measurement signal. Additionally, a perspiration level of skin in contact with the first waveguide may be determined based on the total intensity level of the reflected light in the first waveguide. In one example, an electrical control signal is received from a second photodetector coupled to a second waveguide that is physically isolated from the skin, wherein the total intensity level of the reflected light in the first waveguide is determined further based on the electrical control signal.
