Abstract

A subject light (12) is optically amplitude modulated (14) to generate a sequence of light pulses, each having wavelength components of the subject light. The light pulses propagate through a wavelength dispersive element (18) that spreads the different wavelength components of the pulse in time with a spacing corresponding to the frequency spacing of the components. The time spread light is converted to an electrical signal (20, 22). The time domain form of the electrical signal represents the frequency spectrum of the subject light.
