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.

In the recent years, large improvement is being achieved in the area of decontamination by fog of environmental pollution caused by natural and industrial disasters or attacks with biological, chemical, nuclear weapons of mass destruction. Basic to this technique is the performance of sensors for the existence of pollution and fog in the environment. This article is going to present a small-size and relatively inexpensive instrument, developed by us, which purpose will be to alert the occurrence of visible pollution in air or mist. In that way, it can be controlled, too, whether the cleaning mist has reached all areas. It is possible, that this equipment would assess the density of fog. It works in the infrared spectral region.
