Abstract

Charge coupled device arrays (CCDs) with low noise, small pixel size and high charge storage capacity are available at relatively low cost. Because of this, CCDs are finding increasing use in imaging applications. In this paper we will discuss the performance of a TI-4849 CCD array in an x-ray camera to be used for high-resolution synchrotron radiation tomography. The x-ray image is converted to visible light on a phosphor coated optical face plate which is imaged by a thermoelectrically cooled CCD. The measured modulation transfer function (high-contrast MTF) will be presented for this system. We will describe procedures for choosing and preparing the optimal phosphors for x-ray imaging. Advantages and limitations of CCD arrays over other detectors for tomographic applications will also be discussed.
