Paper Abstract

All the manufacturers of stand-off CWA detectors communicate on the “same” characteristics. And one can find these parameters in the comparison table published between all the different products [1].

These characteristics are for example the maximum detection range, the number of different detectable compounds, the weight, the price, etc…

All these parameters are good to compare products between them, but they omit one very important point: the reaction time in case of an unexpected incoming chemical threat, in the case of the surveillance application.

To answer this important question, we imagine a new parameter: the Field Surface Scanning Rate (FSSR). This value is a classical parameter in astronomical survey, use by astronomers to compare the performance of different telescopes, they compute the quantity of sky (in sky square degrees) analyzed per unit of time by the system.

In this paper we will compare this new figure-of-merit, the FSSR, of some commercially off the shelf stand-off detector. The comparison between classical FTIR system and gas imaging system in term of FSSR will be presented.
