Abstract
Official abstract text for this publication.
A signal digitizing system and method based on analog-to-time optical mapping, optically maps amplitude information of an analog signal of interest first into wavelength information using an amplitude tunable filter (ATF) to impress spectral changes induced by the amplitude of the analog signal onto a carrier signal, i.e. a train of optical pulses, and next from wavelength information to temporal information using a dispersive element so that temporal information representing the amplitude information is encoded in the time domain in the carrier signal. Optical-to-electrical conversion of the optical pulses into voltage waveforms and subsequently digitizing the voltage waveforms into a digital image enables the temporal information to be resolved and quantized in the time domain. The digital image may them be digital signal processed to digitally reconstruct the analog signal based on the temporal information with high fidelity.
First claim
Opening claim text (preview).
We claim: 1. A signal digitizing system based on analog-to-time optical mapping, comprising: an optical pulse source for producing a train of optical pulses; an amplitude tunable filter (ATF) adapted to optically map the amplitude information of the analog signal to wavelength information by impressing on the train of optical pulses spectral changes induced by the amplitude information of the analog signal; a dispersive element adapted to optically map the wavelength informati…
