摘要： A spectrum detecting device including a laser apparatus, an optical splitting apparatus, an optical gate, a first polarizer, a second polarizer, and an optical analysis apparatus is provided. The optical splitting apparatus splits the laser beam providing from the laser apparatus into a first and a second light beam, and the second light beam is transmitted to a sample to produce a spectral signal. The optical gate activated by the first light beam is disposed between the optical analysis apparatus and the sample. The first polarizer is disposed between the sample and the optical gate, and the second polarizer is disposed between the optical gate and the optical analysis apparatus. The spectral signal passes through the first polarizer, the optical gate, and the second polarizer to be transmitted and received to the optical analysis apparatus when the optical gate is activated and turned on in a predetermined time period.
