| 内容記述 | We aim to realize a society in which the passing of daily data contributes to solving social issues, such as achieving Sustainable Development Goals, by establishing highly sensitive and ultra-miniature spectroscopic systems mounted on wearable terminals. Presently, we obtain component data and identify a component using expensive and large equipment at laboratories and specialized institutions after samples are picked up on site. However, if a small and low-cost sensor that measures and identifies components of samples becomes common, the public can obtain component information on site and specialists can receive on-site information from them. An on-site temporal monitoring system of component information would thus be realized. Presently, small sensors mounted on wearable terminals can detect acceleration and illuminance but few other components. Attempts have been made to miniaturize spectroscopic imagers in the visible wavelength region and mount them on smartphones. However, infrared spectroscopic imagers that are appropriate to component analysis have not yet been mounted on smartphones. I establish the wide-field-stop and beam-expansion method, superimposing interferogram method, and point-one-shot Fourier spectroscopy to improve the detected light intensity, the interference definition, and the wavelength resolution of spatial-phase-shift interferometers that can be used as small infrared spectrometers mounted on wearable terminals. Point-one-shot Fourier spectroscopy, which uses only one lens and a camera and one spatial-phase-shift interferometer, detects two-dimensional fringe patterns using point-area information and thus achieves high wavelength resolution using a low-cost low-pixel camera. Conventionally, the sensitivity that is combined using the detected light intensity and interference definition of spatial-phase-shift interferometers is lacking because a field stop is inserted in the optical system and the wavelength resolution and sensitivity of interferometers have a trade-off relationship. However, by combining my three proposed methods, we realize ultra-miniature long-wavelength infrared Fourier spectroscopic imagers that have high sensitivity and wavelength resolution for on-site component identification. | |||||||||||
