| Outline of Final Research Achievements |
In this research, we have studied to develop a resonant grating type optical sensor on palladium surface which can detect hydrogen concentration in a wide range, high sensitivity and high speed, in order to ensure safety for future hydrogen energy society. In order to detect it at high speed, resonance wavelength shift using a spectrometer was measured, and a measurement time of 0.1 s was demonstrated. The highest sensitivity was obtained when the hydrogen concentration was from 1% to 4%, which was higher than the previously reported sensor. The hydrogen concentration resolution was 0.13%. In addition, as a phase difference measurement method for high sensitivity and high speed detection, a method using radially polarized light and a camera, and a method of measuring positional shift between P- and S-polarized beams called Goos-Hanchen shift were studied. Although it was not possible to measure hydrogen, it showed the possibility of high sensitivity and high accuracy.
