Abstract: A reflective grating for the optical diffraction of light rays comprises k juxtaposed, grooved, plane sub-gratings, the planes of the sub-gratings being offset in terms of height with respect to one another along the normal to the plane of the reflective surface of the grooves, enabling the difference in optical path of the grating to be reduced to the difference in optical path between the two ends of a sub-grating.

Abstract: 本発明は、共鳴領域でも有効な新しいブレージングの原理を提案する。本発明では、例えば2連球11a,21a;12a,22aからなる2以上の光散乱ユニットにおいて鏡面共鳴が生じるように、回折格子に光51を入射させ、鏡面共鳴により、第1の層1および第2の層2により回折される回折光52の一部を選択的に増強する。本発明によれば、外部からの制御信号によりブレージング条件をチューニングすることも可能になる。

Abstract: PROBLEM TO BE SOLVED: To flexibly constitute a system without remaking evaluation bases even when change/modification exists in system configuration. SOLUTION: Reusability of the evaluation bases is enhanced and the evaluation bases are flexibly constituted by separating a CPU evaluation base 101, a memory evaluation base 110 and a peripheral circuit evaluation base 116 from one another, mutually connecting them by a hub 109, etc. by using standard network technology (such as TCP/IP and Ethernet) and providing them with consistency by protocol converters 104, 112, 118 which convert a bus protocol and a network protocol.

Abstract: PROBLEM TO BE SOLVED: To reduce an insertion loss and polarization dependency, to widen a wavelength band width, to compactify a size, and to reduce a cost. SOLUTION: A grating used for this multiplexer is constituted to make incident light to each groove reflective, to make emitted lights from the respective grooves intensified each other in a direction of the incident light by an interference effect, to make a wave front of an evanescent wave in the groove parallel to a normal direction of the grating, and to make a migration of the evanescent wave in the groove matched by a groove tube. High diffraction efficiencies are obtained thereby in both TM polarization and TE polarization even in the diffraction order not more than several order, the wavelength band width is widen resultingly, and the polarization dependency is allowed to get small without using a compensation means.

Abstract: PROBLEM TO BE SOLVED: To provide the totally uniform and bright spectral image without affected by the shading by a plane mirror for converting an optical path. SOLUTION: A reflection type Schmidt plate 5 is used, a rotary shaft y1 forming a curved surface of a reflection face of the Schmidt plate and a rotary shaft y2 forming a curved surface of a reflection face of a spherical mirror 6 are same as each other, and the arrangement of the optical elements is determined so that the rotary shaft y2 is shifted from an axis of the incident light of the spherical mirror 6. A spectral image is focused on a detection surface of an optical-detector 7 through the spherical mirror 6, when the luminous flux including the two-dimensional spectral of which the wavelength is dispersed by the echelle diffraction grating 3 and diffraction grating 4 is introduced to the Schmidt plate.

Abstract: PURPOSE: To obtain the diffraction grating which reflects only a basic wave on Bragg diffraction condition and does not reflect waves of high order by using a material consisting of plural elements and laminating one element in a film thickness direction at a constant period so that a sine-functional density distribution is obtained for other elements.
CONSTITUTION: A glass substrate 30 is placed on the substrate holder 14 of a vacuum bell jar 11 and then 180g rhenium 40a and 150g beryllium 40b are put in crucibles 12a and 12b respectively. Then programs of mutual density distributions of the rhenium and beryllium to be vapor-deposited on the substrate in the film thickness direction are recorded in controllers 21a and 21b and then electron guns 13a and 13b are put in operation to emit an electron beam to the rhenium 40a and beryllium 40b, thereby forming alternate phases of the vapor-phase deposited film of those elements which have constant period length R. Consequently, the diffraction grating which has alternate layers where density distributions of the rhenium and beryllium vary in the film thickness direction according to a sine function to the constant period length R is manufactured.
