Title:
位置及び運動を検出するための光電装置及びその方法
Document Type and Number:
Japanese Patent JP4018627
Kind Code:
B2
Abstract:
Optoelectronic device and method for detecting the position and/or movement of an object, the device and method include: a plurality of transmitters for emitting radiation, at least one receiver for receiving the radiation emitted by the transmitters and reflected back by the object or the radiation emitted from transmitters associated with the object, a plurality of mutually different radiation paths, which are formed between at least a part of the transmitters, the object and the receivers or between transmitters associated with the object and the receivers, a timing circuit for cycled switching of the transmitters of the different radiation paths, an evaluation device, which converts the signals received by the receivers for the different radiation paths into values for detection of the position and/or movement of the object along a line or in a surface, wherein for three-dimensional detection of the position and/or movement of the object, the timing circuit switches a plurality of, but at least a part of the transmitters and/or receivers in at least one further cycle such that the space, into which the transmitters emit, is illuminated nearly uniformly, and that the evaluation device determines a value for determination of the distance of the object from the line or surface on the basis of the radiation radiated or radiated back by the object during the further cycle.
