Abstract:
A device and method of optical precision measurement of a component. In the method, an optical probe is provided at a location relative to the component 120 and a source beam directed to the component 122. Deviation is detected 124 and stored in a component characteristic dataset 126. The optical source is moved to other locations relative to the component 128 and additional data acquired 130. The device includes an optical probe 24 providing a source beam 38, a probe stage 22 operable to rotate the optical probe 24 about a O-axis, a component stage 26 operable to rotate the component 28 about a (p-axis, and a position sensitive detector. The probe stage 22 directs the source beam 38 to the component 28, the source beam 38 generates a resultant beam from the component 28, and the position sensitive detector detects the resultant beam. ® KIPO & WIPO 2007

반사면의 표면상태를 결정하기 위한 방법 및 장치를 상술한다. 투영 패턴은 표면에 투영되고, 따라서 형성된 반사패턴을 감지하고 평가한다. 투영패턴의 구조와 반사패턴의 구조의 일치성을 개선시키기 위해 투영패턴에는 연속적인 흑/백 또는 명/암부위를 구별하기 위한 인지표시를 포함한다. 색표시 또는 음영이 특히 유익하다. 눈(3)의 각막 위에 투영패턴을 제공하기 위해 공동 콘모양의 투영체(17)가 사용되는데, 측벽(18)에는 투명링(19)이 배열되어 있고, 링-모양의 광소스(20)에 의해 둘러싸여진다. 칼라 비디오 카메라(26)는 감지기로써 사용된다.
Abstract:
PURPOSE: A method for measuring a shape and a refractive index of a curvature-shaped plastic lens is provided to measure shapes and refractive indexes of several portions with comparative ease by using a digital holography microscope. CONSTITUTION: A method for measuring a shape and a refractive index of a curvature-shaped plastic lens (30) is as follows. A refractive index of a portion of the plastic lens is measured. The measured refractive index is defined as an average refractive index of the plastic lens. Refractive index matching oil (10) which is matched with the average refractive index and relative refractive index oil (20) in which a refractive index is different from the average refractive index are prepared. The refractive index matching oil and the relative refractive index oil are stored in the upper and lower part of a container which is partitioned by the plastic lens. A first phase contrast phase is obtained from a transmission-type digital holography microscope by irradiating lights of a first wavelength to the container from the bottom to the top. A second phase contrast phase is obtained from the transmission-type digital holography microscope by irradiating lights of a second wavelength to the container from the bottom to the top. A third phase contrast phase is obtained from the transmission-type digital holography microscope by irradiating lights of a third wavelength to the container from the bottom to the top.

PURPOSE: An inclined array sensor method measuring a media curl having reinforced accuracy for environmentally caused errors is provided to obtain the function of a sheet curl by measuring a point of a propelled media sheet touching an array for an inclined array sensor. CONSTITUTION: An inclined array sensor method measuring a media curl comprises the following steps: propelling more than one curling media sheet toward an inclined array sensor using nibs of a curler(510); locating the inclined array sensor on the upstream or the downstream of a media propelling device in the angle for the media sheets passing through the curler; obtaining the function of a media sheet curl by measuring a point of the propelled media sheet touching an array for the inclined array sensor(530); and accurately determining the sheet curl using the sheet curl function(540).
