| 英文摘要 | A transmission and reception device for a fiber-optical sensor system functioning with two wavelengths is disclosed wherein light of a first wavelength and light of a second wavelength are supplied over in-coupling fibers of a fiber-optical brancher to a fiber path of the sensor system and wherein light returning over the fiber path is supplied over an out-coupling fiber of the brancher to an evaluation means. The brancher is designed such that the greatest part of the returning light is coupled out over the out-coupling fiber. Two advantageous embodiments of such a brancher are disclosed, the one being designed in the form of a non-frequency-selective, asymmetrical quad-gate brancher and the other being designed in the form of a frequency-selective, five-gate brancher. |
