The Time Stretch Enhanced Recorder (TiSER) ADC takes a high speed analog electronic signal, slows it down by a photonic time-stretch preprocessor, and digitizes that with a relatively slow but high resolution electronic analog-to-digital converter. With this calculator, you will be able to determine the stretch factor, RF bandwidth, and required optical bandwidth amongst other parameters. Please click here to explore further.

Dispersive Fourier Transform (DFT) is an analog technique to map a signal’s spectrum to its time, enabling direct measurement of the Fourier Transform. In the context of optics, this has enabled extremely high-throughput (> 1 MHz), real-time spectroscopy using a wideband pulsed source, the sample itself, a dispersive element, and a fast photodiode. With this calculator, you will be able to calculate the relationship between time and optical color (wavelength or frequency), as well as practical limitations such as spectral resolution, maximum group delay, and dispersive element loss.
