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 the time-stretch dispersive Fourier transform technique, it converts rapidly changing spectral information into a real-time acquisition without the need for mechanical scanning. With a spectral acquisition frame rate of up to 1 billion frames per second, the system can continuously record a large number of pulse spectra in a single experiment, making it especially suitable for capturing high-speed transient processes, non‑repetitive events, stochastic processes, and rare optical phenomena. Compared with traditional scanning spectrometers, this product directly records the continuous temporal evolution of spectra, making it more suitable for studying ultrafast dynamic phenomena that cannot be reliably reconstructed by repeated measurements.
