<p>Provided is a multiplexer for a spectrum monitoring system, including a first disc (110), a second disc (120), and a third disc (130). The first disc is provided with a first light source channel (112) and a plurality of first return light channels (114). The second disc is provided with a plurality of second light source channels (122) and a plurality of second return light channels (124). The third disc is provided with a third light source channel (132) and a third return light channel (134). The third disc can move relative to the first disc and the second disc. When the third light source channel aligns with the locations of the second light source channels simultaneously, the third return light channel can align with the second return light channels and the first return light channels simultaneously. In a multi-probe (60) monitoring system, the intensity of the required light source (80) can be reduced, the number of spectrometers (90) can be reduced, and the errors and losses of the multiplexer caused by optical path switching can be avoided.</p> |
