Abstract
A temporal magnification spectrometer includes a dual-chirp comb source, a signal leg, a local oscillator leg, an optical detector, and a temporal magnification analyzer. The dual-chirp comb source produces optical carrier laser light. A signal comb having signal linearly chirped waveforms interacts with a sample to produce a transmitted signal comb. The local oscillator leg produces a local oscillator comb having local oscillator linearly chirped waveforms. The optical detector receives the transmitted signal and local oscillator combs and produces an RF domain signal. The analyzer receives and Fourier transforms the RF domain signal to produce an RF comb, which is sampled to produce sampled RF comb lines, which are normalized to produce temporally magnified sample frequency domain data. Intermediate sample temporal data are normalized to produce a steady-state sample spectral response.
