Abstract

A method of determination of a property of an optical device under test includes using a first initial coherent light beam, changing a first initial property of the first initial light beam, coupling the first initial light beam to the device under test, detecting a first signal of the first initial light beam received from the device under test, and correcting any a non-linearity in the first signal by interpolating the first signal on a linear scale.
