Pockels readout optical modulator: An x‐ray imaging detector that maintains good efficiency over a broad energy range
We present measurements of the performance of a Pockels readout optical modulator (PROM) x‐ray imaging detector using a 30‐kV constant potential bremsstrahlung source. A nickel step wedge was used to measure the spatial resolution and noise of the PROM image. PROMs are unique high‐efficiency x‐ray d...

Zusammenfassung: | We present measurements of the performance of a Pockels readout optical modulator (PROM) x‐ray imaging detector using a 30‐kV constant potential bremsstrahlung source. A nickel step wedge was used to measure the spatial resolution and noise of the PROM image. PROMs are unique high‐efficiency x‐ray detectors that image with good spatial resolution over a wide range of x‐ray energy. The PROM is constructed from an optically transparent, active crystal that is sensitive to x‐ray dose. This unique construction allows the use of a thick crystal to increase efficiency for x‐ray detection while avoiding the spatial resolution degradation that usually accompanies thick detectors. |
