Detector is the same as what?

• A. Receptor
• B. Sensor
• C. Transducer
• D. Pixel array

Answer: (A)

The detector is the same as the receptor. In imaging systems, the detector’s job is to receive the incoming signal and convert it into a form the system can use to produce an image. The image receptor is the device that records that image, whether on film or a digital medium. Because they both refer to capturing and conveying the image data, these terms are used interchangeably in this context. A sensor is a more general term for any device that detects changes, but it isn’t necessarily the image-recording component. A transducer converts energy from one form to another, which is related but not exactly the same role as the detector. A pixel array is the layout of sensing elements inside the detector, not the detector as a whole.
