1. The controller receives timing signals either from the computer or from external trigger sources and accordingly sends control signals to the camera to begin and end image acquisition. After images are acquired in the CCD array, the analog image data is downloaded to the controller where it is digitized and directed to the PC for storage as a data file. Digitization is accomplished by a 12-bit analog-to-digital converter such that the light intensity recorded by a CCD pixel is rendered as an integer ranging from Oto 4095. The units of digitized intensity are referred to as counts. The accuracy of the analog-to-digital converter as reported by Roper Scientific is 1-1.6 counts RMS and the linearity deviates by less than two percent.10
