Charged coupled device (CCD) image sensors are electronic devices that are capable of transforming a light pattern (image) into an electric charge pattern (an electronic image).
Photosensor modules are compact light detectors with built-in power supplies. They use photomultiplier tubes, avalanche photodiodes, PN photodiodes, or PIN photodiodes.
Power supplies are devices that produce AC or DC power. This grouping includes current sources, DC power supplies, AC-DC adapters, DC-DC converters, AC power sources, and DC-AC inverters.
