Single-Shot Billion Frame-Rate Optical Spectrometer

The single-shot billion frame-rate optical spectrometer is a real-time single-shot spectral measurement system designed for ultrafast optics, laser dynamics, and nonlinear optics research. Based on time-stretch dispersive Fourier transform technology, the system can convert and acquire rapidly varying spectral information in real time without scanning. With a spectral acquisition frame rate of up to 1 billion frames per second, it can continuously record a large number of pulse spectra in a single experiment, making it particularly suitable for capturing high-speed transient processes, non-repetitive events, stochastic processes, and rare optical phenomena. Compared with traditional scanning spectrometers, this product can directly record the continuous evolution of spectra over time, making it more suitable for studying ultrafast dynamic phenomena that cannot be stably reconstructed through repeated experiments.
