Device that stores information in the form of charge packets in an array of closely spaced capacitors.
Notes:
  1. The packets can be transferred from one capacitor to the next sequentially by electronic manipulation, so that the information contained in the array can be sequentially read electronically.
  2. In spectroscopy, the charge packets are created by interaction with electromagnetic radiation and the devices are extremely sensitive detectors for near infrared and visible radiation.
