Abstract
Proposed is a spectroscope including a disperser configured to disperse incident signal light, wherein the disperser includes a bandpass filter configured to spectroscopically process the signal light by pivoting according to a driving signal and a light-receiving element configured to receive the signal light spectroscopically processed by bands and output a corresponding electrical signal.
Claims16
A spectroscope comprising:
- a disperser configured to disperse incident signal light, wherein the disperser includes:
- a bandpass filter configured to spectroscopically process the signal light by bands, by pivoting according to a driving signal;
- a light-receiving element configured to receive the signal light spectroscopically processed by bands to output a corresponding electrical signal;
- a mixer that receives the electrical signal from the light-receiving element and the driving signal for pivoting the bandpass filter and mixes the electrical signal and the driving signal;
- an electrical filter that outputs a signal of a target band from a signal output from the mixer;
- and
- an amplifier that allows the electrical signal output from the light-receiving element to be amplified and outputs the amplified electrical signal to the mixer,
- wherein the mixer performs a down-conversion of the amplified electric signal output from the amplifier using the driving signal for pivoting the bandpass filter.
