New reactive azo dyes are described which are useful for optical determination of pH. The dyes are covalently linked (via ethylsulfonyl groups) to a novel type of transparent solid films consisting of a thin film of cellulose on top of a polyester support. The resulting membranes exhibit distinct co

## Abstract A novel variable optical attenuator (VOA) based on high‐birefringence (HiBi) fiber‐loop mirror is proposed. The HiBi fiber‐loop mirror is put into the temperature‐controlling box. As the temperature increases, the transmission spectrum shifts with nearly unaltered shape. The attenuation
## Abstract A novel digital active homodyne demodulation scheme to eliminate the signal fading in interferometric fiber‐optic sensors is proposed. The error signal is obtained by the square‐wave phase modulation and then the digital correlation detection technique is applied to demodulate the low‐f
