Abstract

We have developed a digital readout system for radiographic images using a scanning laser beam. In this system, electrostatic charge images on amorphous selenium (alpha-Se) plates are read out using photo-induced discharge (PID). We discuss the design requirements of a laser scanner for the PID system and describe its construction from commercially available components. The principles demonstrated can be adapted to a variety of digital imaging systems.

摘要

我们开发了一种使用扫描激光束的射线图像数字读出系统。在该系统中，利用光致放电（PID）读出非晶硒（α-Se）板上的静电荷图像。我们讨论了用于PID系统的激光扫描仪的设计要求，并描述了其由商用组件构成的结构。所展示的原理可适用于各种数字成像系统。
