  • Patent number: 6768553
    Abstract: The present invention provides a continuous-zoom imaging device of an interferometer. Reflected lights of a reference plane and a test plane interfere with each other to generate an interference pattern. A collimation device converts a parallel light of the interference pattern into a convergent light. An optical path adjustment means guides the light to a polarizing beam splitter. A continuous-zoom device adjusts the magnification ratio of the interference pattern on the imaging passageway and to output an object image, which is then imaged on a charge-coupled device. The present invention can improve the quality of the interference pattern without using any rotating diffuser, and thus has the characteristics of reduced number of components, lowered cost, and shrunk volume. Besides, the present invention can utilize a joint device to connect the continuous-zoom device and an attenuator so as to achieve automatic light adjustment and convenient operation.

  • Patent number: 6665064
    Abstract: To detect the relative position of bodies, surfaces or the like, especially those on machines, there is an optoelectronic sensor. The latter reacts to incident light, for example, monochromatic laser light. The available receiving surface is however comparatively small for low-cost or pixel-oriented sensors. By making available a diffuser and a projecting objective lens in front of an optoelectronic sensor the usable receiving surface for incident light can be greatly increased. The diffuser or also the projecting objective lens can additionally be designed as a color filter and can be used to reduce the effects of outside light. A process is provided with which an especially accurate determination of the median point of the laser light spot incident on the target (optoelectronic sensor) can be achieved.

  • Patent number: 5392111
    Abstract: An optical axis of a headlight is measured by disposing a lattice member in front of the headlight. The lattice member has a plurality of longitudinally elongated lattice holes which are arranged in a form of a matrix. An illuminated area and an illuminance of light beams to be transmitted through the lattice member are measured at each of illuminating regions which are divided into a form of a matrix by the lattice holes. The position of a light source of the headlight is located from an illuminating region of maximum illuminated area and a position of an optical axis of the headlight is located from an illuminating region of maximum illuminance. The optical axis is adjusted depending on the located position of the light source and the position of the optical axis such that the inclination angle of the optical axis coincides with a set inclination angle. An illuminance distribution pattern is used to judge the type of headlight during adjustment of the optical axis of the headlight.
