摘要： PROBLEM TO BE SOLVED: To provide a wavelength splitter which replaces general dichroic mirrors (or splitters) and has a high optical damage resistance in a harmonic laser beam generator. SOLUTION: The harmonic laser beam generator uses a transmission diffraction grating composed of quartz glass as a wavelength splitter. Since the optical damage of a wavelength splitter can be made lower because the quartz material has a very low optical absorption, the optical damage resistance can be made higher, thereby providing a high-power harmonic laser beam generator.

摘要翻译：要解决的问题：提供一种用于代替一般二向色镜（或分离器）并且在谐波激光束发生器中具有高光损伤电阻的波长分离器。
解决方案：谐波激光束发生器使用由石英玻璃作为波长分光器组成的透射衍射光栅。由于由于石英材料具有非常低的光吸收，因此波长分配器的光学损伤可以降低，可以使光学损伤电阻更高，从而提供高功率谐波激光束发生器。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To estimate the presence of a deposit deposited on a detection face, a kind of the deposit, and a state of the deposit. SOLUTION: Light via the detection face is image-focused by a lens, and photoreceived by a photoreceiving element part arrayed with plural micro photoreceiving elements. Total reflection light from the detection face is photoreceived by the photoreceiving element part in a deposit detecting mode. The each element is arranged at an angle where total reflection is satisfied when no deposit exists, and where the total reflection is not satisfied in the presence of the deposit. Scattered light from the detection face is photoreceived by the photoreceiving element part in a light scattering deposit detecting mode. Detection signal levels of the respective micro photoreceiving elements are coupled in response to an array of the micro photoreceiving elements to obtain a signal pattern. An increase portion and a decrease portion of the signal pattern in response to a difference in the presence and state of the deposit are analyzed to estimate the kind and state of the deposit such as a rain drop, mud water, fogging, freezing and the like.
