Abstract
Provided is an imaging apparatus including: a splitter that splits incident light into pieces of light of two or more wavelength bands; and two or more detectors that detect the pieces of light of two or more wavelength bands respectively and output signals from which wavelengths can be extracted tunably by post-processing.
Claims18
An imaging apparatus comprising:
- a splitter that splits incident light into pieces of light of two or more wavelength bands, the wavelength bands including a first wavelength band of light of a visible wavelength and a second wavelength band of only light of wavelengths longer than the visible wavelength;
- and
- two or more detectors that respectively detect the pieces of light of two or more wavelength bands, the two or more detectors including a first detector for the first wavelength band and a second detector for the second wavelength band, and that output signals from which wavelength bands can be extracted tunably by post-processing.
A signal processing apparatus comprising:
- acquisition circuitry configured to acquire signals output by two or more detectors respectively having detected pieces of light of two or more wavelength bands split from incident light by a splitter, the wavelength bands including a first wavelength band of light of a visible wavelength and a second wavelength band of only light of wavelengths longer than the visible wavelength, the two or more detectors including a first detector for the first wavelength band and a second detector for the second wavelength band;
- and
- a signal processor configured to extract signals of a desired wavelength band using the signals.
A signal processing method to be executed by a computer, the method comprising:
- acquiring signals output by two or more detectors respectively having detected pieces of light of two or more wavelength bands split from incident light by a splitter, the wavelength bands including a first wavelength band of light of a visible wavelength and a second wavelength band of only light of wavelengths longer than the visible wavelength, the two or more detectors including a first detector for the first wavelength band and a second detector for the second wavelength band;
- and
- extracting signals of a desired wavelength band using the signals.
A non-transitory computer readable medium storing a program, the program being executable by a computer to perform operations comprising:
- acquiring signals output by two or more detectors respectively having detected pieces of light of two or more wavelength bands split from incident light by a splitter, the wavelength bands including a first wavelength band of light of a visible wavelength and a second wavelength band of only light of wavelengths longer than the visible wavelength, the two or more detectors including a first detector for the first wavelength band and a second detector for the second wavelength band;
- and
- extracting signals of a desired wavelength band using the signals.
