ABSTRACT:
An optical property of a device under test is determined from a detected DUT response signal, or a signal derived therefrom, whereby the DUT response signal represents a signal response of the DUT in response to a composite signal or a signal derived from said composite signal. The composite signal comprises superimposed signals delayed with respect to each other.
