Abstract

Measurement device, specifically developed to capture and quantify low-amplitude surface photo-charge effect signals. It can also modulate and power a laser in various modes, and extract the processed signal as an output. The device is compatible with all of our surface photo-charge effect-based systems. The device is part of a portable system for detection of pollution in fogs or aerosols.
