The scope of this study is to investigate the utilization of optical and acoustic emissions, originating from processing zone, for real-time monitoring of the percussion laser drilling process. For that purpose, an acoustic microphone and photodiodes were off-axially arranged relative to the laser beam and for both types, correlation between the sensor output and the hole geometry is theoretically investigated. Results are compared with experimental data.
