文摘
- •
Tunable holographic sensors for relative humidity and temperature monitoring are proposed.
- •
Operation range, sensitivity and reversibility can be adjusted by variation of the photopolymer composition.
- •
Increased humidity and temperature response is achieved by use of diacetone acrylamide-based photopolymer.
- •
Lack of sensitivity to humidity and temperature is achieved in gratings recorded in N-phenylglycine containing photopolymer composition.
