We have developed a Monte-Carlo photon-tracking and readout simulator called SCOUT to study the stochastic behavior of signals output from a simplified rectangular scintillation-camera design. SCOUT models the salient processes affecting signal generation, transport, and readout. Presently, we compare output signal statistics from SCOUT to experimental results for both a discrete and a monolithic...
Single Photon Avalanche Diodes (SPADs) create a very short duration voltage pulse whenever a photon is detected. The resulting high sensitivity and temporal resolution makes them useful in a range of applications. In this paper two different analogue circuits are reported that are suitable for imaging applications that can record the number of detected photons in the limited area available between...
An intensity modulated fiber-optic position sensor, based on a fiber to bundle coupling and a readout system using a CMOS image camera together with fast routines for position extraction and calibration, is experimentally demonstrated. Further, a simulation of the complete sensor system setup is made, and possible sources of error are analyzed experimentally. Our analysis indicates the theoretical...
