Abstract
Methods and system for signal sampling using spatial dispersion are disclosed. In an example, a system includes a time-to-wavelength dispersion system configured to generate a wavelength dispersed optical pulse that is modulated according to an input signal, a wavelength-to-space dispersion system configured to spatially disperse the wavelength dispersed optical pulse by wavelength to produce a spatially dispersed optical pulse, a Fast Fourier Transform (FFT) optical system configured to transform the spatially dispersed optical pulse into a frequency domain transformed optical pulse, a sensor system configured to convert the frequency domain transformed optical pulse to electrical signals, the sensor system including a two-dimensional (2D) array of photodetectors, and a processor configured to determine frequency information about the input signal from the electrical signals.
