Abstract
A high sensitivity optical radiation detecting system, with spatial re solution, has been developed. The system consists of two optical ampli fiers (image intensifiers tubes) coupled to sensitive video (CCD) came ra. The signal from the camera is digitised through a fast analogue to digital converter (frame grabber) and transferred to personal compute r. The system can detect less than a nano-lux (similar or equal to pho ton/pixel) of radiation with 512 x 512 spatial resolution and 256 gray scale. The system has many applications. Its application for conversi on of a red-time high bandwidth oscilloscope to a fast transient digit iser (or digital storage oscilloscope) is reported by capturing and di gitising the faint trace on the oscilloscope screen.
