7.0 Application of Back-illuminated CCD Technology . As indicated in the absolute performance characterization detailed above, low noise, back-illuminated, low light level CCD (BCCD) cameras offer superior low light level performance to image intensified approaches. ... Figures 7.3 and 7.4 show a similar test of bar targets clearly illustrating the superiority of the back-illuminated CCD for low light level imaging of high resolution targets at a range of 400 meters. ...
