Optical determination arrangement for analysis of optical signals, and optical sensing system

摘要

The invention in particular provides an optical determination arrangement (40) for enabling determination and analysis of a plurality of output signals of optical nature, wherein each one of said output signals comprises light of a unique optical wavelength assigned to said output signal. The arrangement comprises a multiplexing unit (50) for multiplexing the output signals into a common signal, and a receiver unit (85) for receiving said common signal and for determination of said output signals comprised by said common signal for enabling analysis thereof. In particular, the determination arrangement (40) comprises a modulator unit for modulating each one of said output signals with a unique modulator signal assigned to each output signal. Furthermore, the receiver unit (85), for enabling said determination, comprises a demodulator unit for demodulating each one of said output signals from said common signal using said modulator signal.
