Abstract
An optical measurement system sensitive to light field amplitude is disclosed. The system uses an interferometer while a feedback loop maintains, at a low level, the light intensity exiting from at least on optical output of the interferometer. Shot noise of a detector placed at the output of the interferometer is thus reduced, enabling high speed and high accuracy measurement without requiring is stronger light source. The measurement system may be used in optical computing.
