In a common computed radiography plate reader, which combination of components is used to convert the captured signal to digital form?

Explanation:
Translating the light signal detected from the plate into a digital image starts with an analog electrical signal that is proportional to the light intensity captured by the detector. To turn that continuous signal into digital data for processing and storage, you use an Analog to Digital Converter. The light coming from the plate must be efficiently directed onto the detector to maximize signal strength and preserve spatial information, and that’s where a focusing lens comes in—the lens gathers and concentrates the emitted light onto the detector. A focusing cup is related to electron optics inside a photomultiplier tube and isn’t used for directing light onto the detector in this context, and a digital to analog converter would convert digital values back to analog, which is the opposite of what’s needed.
