摘要： A position measurement system includes a marker set attached to an object, a camera and a computing apparatus. The marker set includes three or more directed basic markers each having a shape indicating a direction. The directed basic markers are oriented in directions toward a specific point. A positional relationship among the directed basic markers is known. The camera includes a two-dimensional imaging device configured to take an image of the marker set. The computing apparatus computes at least one of a position of the object and an angle of the object based on an image, taken by the camera, of the directed basic markers, which are oriented in the directions toward the specific point.

摘要： A position measuring system including a laser light source for radiating a laser beam, an optical lens system for generating an interference pattern on the basis of the laser beam having passed through different optical paths, a detector for detecting the interference pattern, and an arithmetic unit for calculating the position of at least one of the light source and the detector on the basis of a detection signal issued from the detector. For example, a spherical lens can be used as the optical lens system. In this case, the interference pattern is formed on the basis of spherical aberration of the lens. Alternatively, a multifocal lens may be used as the optical lens system.

摘要： A position measurement system optically measures a position of an object in a simple manner at low cost. The position measurement system includes: a light source; an optical lens with a large spherical aberration which transmits light from the light source and forms a light ring due to its spherical aberration; a light receiving device (CCD sensor) which detects the light ring as formed by the optical lens; and a calculator which measures a position of the light source according to detected information on the light ring as detected by the CCD sensor. An optical mirror with a large spherical aberration may be used instead of the optical lens.

摘要： A master device and a slave device are each constituted of a transmitting section; a receiving section; and a control section including a three-dimensional position calculation section for calculating a three-dimensional position of the transmitting section of the counterpart master device or that of the counterpart slave device and an element drive section for driving an MEMS element. First, the master device outputs transmission light having comparatively narrow directivity, and the transmission light is two-dimensionally scanned. Next, the receiving section of the slave device receives that transmission light, calculates the transmission direction of the master device from the position of a spot of transmitted light on a light-detecting element array, and transmits the transmission light in that direction. At this point in time, scanning of the transmission light from the master device is stopped, and subsequently communication is initiated.
