The phone-or 3D optical energy density probe: calibration test report of the modified/re-calibrated probe

Abstract

This report discusses the results from the second calibration test performed on the Phone-Or 3D optical Energy Density probe. The first calibration test found several performance issues associated with high level of noise in the Phone-Or probe. Since then, the Phone-Or manufacturer has addressed those issues by modifying and re-calibrating the probe. To investigate the current performance of modified/re-calibrated probe, a second calibration test was performed in the Anechoic chamber at the University of Adelaide. The test results show that the Phone-Or probe's performance has improved considerably with its self-noise level, particularly due to 50 Hz harmonics, been reduced significantly.
