Integrated near-infrared fiber-optic photoacoustic sensing demodulator for ultra-high sensitivity gas detection
An integrated near-infrared fiber-optic photoacoustic sensing demodulator was established for ultra-high sensitivity gas detection. The demodulator has capacities of interference spectrum acquisition and calculation, laser modulation control as well as digital lock-in amplification. FPGA was utilize...
