a Compact, Selective and Embedded-System Enabled Photoacoustic Sensor for Multiple Trace Detection (JW1A.147)

Presenter: Xueshi Zhang, Xidian university

A compact, selective and embedded-system enabled photoacoustic sensor was established with self-designed modules which replaced laser controller, signal generator and Lock-in Amplifier. The results exhibit that normalized noise equivalent absorption (NNEA) coefficient achieves 2.12×10-8cm−1W/Hz−1/2.
