| 摘要 |
<p>This invention discloses an optical spectrometer and a method for enhancing signal intensity for optical spectroscopy. The spectrometer includes: a light source and sampling unit, adapted to emit light and project the light onto a sample; an optical signal pre-processing unit, adapted to receive the light from the sample and output phase-division multiplexed and spatially decoupled optical signals in multi-channels; an optical signal encoder, adapted to allow optical signals of one or more channels among the multi-channels to pass through and reject optical signals of the rest of the multi-channels according to an encoding pattern; and a detection unit, adapted to acquire optical signals from the one or more channels passing through the optical signal encoder. The apparatus and method provided in the present invention can operate effectively with a weak throughput and achieve better operational reliability.</p> |
