Duping arrangement for laser distance measuring devices |
摘要 |
A duping arrangement is provided for a laser distance measuring device in which the illuminated object sends to the transmitter an identical but time-delayed signal and, therefore, supplies the transmitter with an incorrect distance reading. The duping arrangement comprises a wide-angle optical system formed by a bundle of glass fibers, a fiber delay line and a phase-conjugated optical element that is operated in an externally pumped mode or a self-pumped mode.
