Review on Speckle-Based Spectrum Analyzer
نویسندگان
چکیده
Abstract Accurate spectral measurement and wavelength determination are fundamental vital for many fields. A compact spectrum analyzer with high performance is expected to meet the growing requirements, speckle-based a potential solution. The basic principle based on using random medium establish speckle-to-wavelength mapping relationship reconstruction. This article introduces current analyzers different schemes reviews recent advances in this field. Besides, some applications by also introduced. Finally, existing challenges future prospects of speckle recovery discussed.

Qubits have been used as linear spectrum analyzers of their environments. Here we solve the problem of nonlinear spectral analysis, required for discrete noise induced by a strongly coupled environment. Our nonperturbative analytical model shows a nonlinear signal dependence on noise power, resulting in a spectral resolution beyond the Fourier limit as well as frequency mixing. We develop a noi...
