Detector Array

Definition

A detector array is a collection of multiple sensors arranged in a specific configuration that collectively capture and process information about light or other radiation. This setup enhances the detection capabilities by improving spatial resolution and enabling simultaneous measurement of different signals, making it particularly useful in advanced imaging techniques like quantum ghost imaging.
