Hard Surface Scatter Models

Hard Surface Scatter Models

Eritek has developed and validated hard surface and atmospheric scatter models.  Continued development of additional capabilities and features to these models is currently funded under a classified Government contract

A hard surface scatter model has been developed that calculates the amount of light scattered off multiple surfaces when a beam is directed into a room through a window.  A combination of specular and nearly lambertian scatter is produced when the laser beam strikes these surfaces.  The geometry of the entire scene is input into the model along with its orientation to the sun.  Background light from the sun, both direct and diffuse, is also calculated.

These models have been validated over the last several years under various configurations (ranges, times of day, weather conditions, etc.) with several field tests using a computer automated LabView camera collection and analysis program.
