Abstract

Electron-optical devices are broadly used nowadays in experimental physics, technology research and technical applications for high-speed recording. Fast processes can be studied with these devices in framing and streak modes1, thus giving vast information on the spatiotemporal evolution of optical fields in a broad spectral range. Especially, in the visible, ultraviolet (X-ray) and near infrared (IR) spectral ranges, these methods are efficient. But unfortunately, many of them lose sensitivity for wavelengths of incoming light larger than λ > 1.3 µm. In this contribution we present a technique that will allow spatio-temporal resolved high-speed recording even at wavelengths beyond 1.3 µm. We will also demonstrate, that this technique can be used for the spatially and temporally resolved measurement of temperature distributions on the surface of heated bodies.
