摘要： In a method of making a replication tool, replication parts for both two dimensional optical elements, such as are fabricated using micro-forming techniques, and three dimensional optical elements, that are typically formed using cutting techniques are present on the replication tool. A method of manufacturing a replication tool for a planar optical sheet includes mounting at least one optical element part on a bse to form a master part and forming a conductive metal layer over the master part. The method also comprises electrochemically depositing over the conductive metal layer to form an electrochemically deposited layer, separating the electrochemically deposited layer from the master part. The invention also relates to the replication tool itself and optical circuits formed using the replication tool.

摘要： A method and apparatus are presented for aligning a diffractive WDM device that includes i) a multi-channel, light handling device having a selected channel spacing and ii) a multi-channel signal input unit. The method includes adjusting a direction of incidence of an optical signal from the input unit on at least a first diffracting element of the WDM device so as to set an actual optical channel spacing at an output region of the WDM device to be approximately equal to the selected channel spacing of the multi-channel, light handling device. In the apparatus, the orientation of the light input unit is adjustable in a direction parallel to a diffraction plane of the diffractive WDM device so as to select an actual channel spacing at the multi-channel, light handling device that is approximately equal to the selected channel spacing.

摘要： The present invention relates to a compact and inexpensive optical displacement sensor that does not require accurate control of the distance to the object. A repetitive optical structure is utilized for formation of a repetitive optical signal emitted by an illuminated moving object. The repetitive optical structure is illuminated by the light source for formation of a fringe pattern (similar to Laser Doppler Anemometry), and/or, an object is illuminated by the light source and the repetitive optical structure diverts light from the illuminated object onto light sensors. A speckle pattern is formed on the object by the illumination. The speckle pattern moves with movement of the object, and speckle pattern movement is determined without a need for imaging the object onto the repetitive optical structure. Since the speckle pattern is not imaged onto the optical member, the distance and possible distance changes between the object and the optical member substantially do not affect system performance.
摘要翻译：本发明涉及一种紧凑而廉价的光学位移传感器，其不需要精确地控制到物体的距离。重复的光学结构用于形成由照明的运动物体发射的重复光信号。重复的光学结构由光源照射以形成类似于激光多普勒测风法的条纹图案，和/或物体被光源照射，并且重复的光学结构将光从被照射物体转移到光传感器上。通过照明在物体上形成斑点图案。斑点图案随着物体的移动而移动，并且确定斑点图案移动，而不需要将物体成像到重复的光学结构上。由于斑点图案不成像到光学构件上，物体和光学构件之间的距离和可能的距离变化基本上不影响系统性能。
