摘要： A polar coordinate-based profilometer includes a base, a rotary stage, a linear stage, and a probe device. The rotary stage is mounted on the base and includes a rotary table rotatable about a vertical axis oriented orthogonal to the base. The linear stage is mounted on the rotary table and is rotatable therewith. The linear stage includes a linear slide member that is translatable along a radial axis orthogonal to the vertical axis. The probe device is mounted on the linear slide member and is translatable therewith. The probe device includes a probe tip that is linearly displaceable along the radial direction and communicates with a linear displacement-sensing transducer. Alternatively, the probe device scans an object without contacting the object. Methods are provided for measuring an object based on polar coordinates, and correcting for misalignment prior to measurement.

摘要： A microlens array is formed with lenses having many different symmetries to produce a large number of light output pattern shapes. The portions of the microlens array lenslets that direct light into undesirable locations are replaced with additional lenslets that redirect the light to where it is wanted. The microlens array has a plurality of primary lenslets on a substrate, the primary lenslets being curved shapes. Each of the primary lenslets has a surface area and a peripheral region. A plurality of secondary lenslets are at the peripheral regions of the primary lenslets and have surface areas which are smaller than the surface areas of the primary lenslets. The primary lenslets have a first vertical dimension and the secondary lenslets have a second vertical dimension which is smaller than the first vertical dimension. Tertiary lenslets may also be included in the microlens array. In the second of two described embodiments, the secondary and tertiary lenslets present convex cross-sectional shapes.

摘要： A motion sensor has a pyroelectric detector, a Fresnel lens array, a reducing lens, and a housing. The detector has two elements located side-by-side and the lens array has a plurality of lenslets which are integrally formed. The reducing lens demagnifies the elements. The reducing lens has grooves which run in parallel directions and face toward the elements. The lens array illuminates the detector by focusing infrared light through the reducing lens and onto the elements. The reducing lens makes the elements appear smaller and closer together. The reduced image of the detector allows the lenslets to be spaced more closely than prior art lenslets, thereby making the angular separation less than the angular separation of prior art sensors. Alternatively, the detector housing may be made smaller while maintaining the same angular separation of prior art sensors. If an object moves between two zones, the sensor detects the movement and triggers an alarm, turns on a light, or initiates some other process.

摘要翻译： 运动传感器具有热电检测器，菲涅尔透镜阵列，还原透镜和壳体。 检测器具有并排定位的两个元件，透镜阵列具有多个整体形成的小透镜。 还原镜减少了元件。 还原透镜具有沿平行方向延伸并朝向元件的凹槽。 透镜阵列通过将红外光聚焦通过还原透镜和元件照亮检测器。 还原透镜使元件看起来越来越小。 检测器的缩小图像允许小透镜比现有技术的小透镜更紧密地间隔开，从而使得角分离小于现有技术传感器的角度间隔。 或者，可以使检测器壳体更小，同时保持现有技术传感器的相同的角度间隔。 如果物体在两个区域之间移动，则传感器检测到移动并触发警报，打开灯或启动其他过程。
