Digital Fluence Profiling System and Software

Source

An advanced digital fluence profiling system based on a windowless GE TN2502 or TN2509 silicon array camera and Poynting Products 505RM frame grabber is described. The camera array is located precisely in the target plane or equivalent, and synchronized to the pulsed laser source with a flashlamp radiation sensor circuit. Data acquired by the frame grabber are transferred to an HP Series 200 computer for analysis.

Analysis is performed with BEAMCODE 2.0 software which permits near real time extraction of the peak fluence to total energy ratio in a single pulse to better than 20 percent. When corrected to camera nonuniformity and compared to large-aperture calorimetry, accuracy exceeds 10 percent. Other functions include measurement of pointing stability (beam wander) and divergence, fit-to-gaussian, and graphics data displays in contour and pseudo-3D formats.
