Abstract
A spectrometry device includes a switch and a converter. The switch acquires a first reception signal and a second reception signal that respectively include information relating to an optical spectrum and switches between outputting the first reception signal and outputting the second reception signal based on control by a controller. The converter converts the first reception signal or the second reception signal output from the switch into a digital signal.
Claims11
A spectrometry device, comprising:
- a processor that:
- acquires a first reception signal and a second reception signal that respectively include information relating to an optical spectrum,
- controls switching between outputting the first reception signal and outputting the second reception signal,
- converts the switched-to first reception signal or the second reception signal into a digital signal,
- causes a second time period to be shorter than a first time period when converting the switched-to first reception signal or the second reception signal into the digital signal, wherein
- conversion of the first reception signal is repeated during the first time period, and
- conversion of the second reception signal is repeated during the second time period,
- adds a repetition of the second time period,
- determines whether the added repetition of the second time period arrives at a predetermined time period set in advance, and
- analyzes the optical spectrum based on the converted second reception signal during the added repetition of the second time period when it is determined that the added repetition of the second time period arrived at the predetermined time.
