1. An integrated nondestructive sensing device for inspection and measuring the cleanliness of composite surfaces coupled with laser ablation for removing contaminants and activating the composite surfaces comprising:
a. a pulsed laser ablation system to prepare and clean the composite surfaces;
b. a secondary electron sensing system using a short wave ultraviolet light to generate secondary electrons from the composite surfaces to generate a measurable current that is directly proportional to the cleanliness and activation of the surface;
c. wherein the secondary electrons are collected via a mesh collector connected to a virtual ground and the secondary electron current is measured by an ammeter; and
d. wherein the composites surfaces are biased to ground with a negative DC power supply.
