Abstract:
하나의 양상에서, 가령 파로시아미터(Parosiameter)와 같이 스캐터로미터(100)로부터 얻어진 영상 세기 데이터를 저장 할 필요가 있는 데이터의 양은 상기 광도 데이터가 광도에 대한 변화에 따라 그리드의 다른 영역에서 사용되는 해상도를 변화시킴으로써 줄어든다. 또 다른 양상에서, 스캐터로미터는 상기 테스트 샘플에 대한 거울의 중심이 벗어난 배치에 의해 도입된 왜곡을 수정하기 위해 테스트 샘플(180)을 영상화하는 비구면 거울(170,900,1000)로 제공된다. 또 다른 양상에서, 광학 표면 검사 장치는 상기 테스트 표면상에 패턴 그리드(1610)를 투사하기 위하여 테스트 표면(1420)과 조명된 패턴 그리드(1410) 사이에 보조 렌즈(1440)를 사용한다. 카메라(1450)는 실제의 영상으로서 상기 테스트 표면상의 그리드에 초점이 맞춰진다.
Abstract:
A system comprising: a dielectric configured to: a) create a bi-periodic interference pattern of two standing sinusoidal waves on illumination by two pairs of counter-propagating light beams at different incident angles, wherein the incident angles are selected in accordance with the index of refraction of the dielectric to i) to determine the spatial frequency of each counter-propagating light wave pair, and ii) cause total internal reflection, and b) generate, from the bi-periodic interference pattern, an evanescent bi-periodic standing sinusoidal wave; a light source configured to illuminate the dielectric with the two pairs of counter-propagating sinusoidal light waves at the selected incident angles and thereby illuminate a fluorescing object positioned at the surface of the dielectric with the generated bi-periodic evanescent standing sinusoidal wave; and one or more delay lines configured to independently modify the initial phase of each counter-propagating light wave pair.

Abstract:
The invention relates to a method and an apparatus for the investigation of a sample material that is stored in the sample chamber (303) of a storage unit (300). A multi-spot generator MSG (100) and a transmission section (200) generate an array of sample light spots (501) within the sample chamber. Input light (504) that leaves the storage unit (300) in forward direction is mapped onto a CCD array (401) and measured as reference. Moreover, fluorescence light (500) that is stimulated in the sample chamber (303) is measured by a second CCD array which is disposed perpendicular to the optical path of the input light (504).
Abstract:
This invention is provided with means (13, 14) for projecting the light reflected on a striped pattern onto a tape (15), and a means (19) for inspecting a wrinkle by analyzing the pitch of the striped pattern projected onto the tape (15) on a plurality of inspection lines, so as to enable the variation of a minute wrinkle to be detected in a short period of time.
