Its optical set up and laser source have been specifically optimized to operate with the high speed camera FASTCAM NOVA by Photron. This system offers hologram recording rates up to 12’800 frames per second (fps) at megapixel resolution, 40’000 fps at a resolution of 512×512 pixels, and 116’000fps at 256×256 pixels.
A dedicated and intuitive software interface, fully integrated in our Koala acquisition and analysis software, enables to control the high speed camera parameters (acquisition framerate, shutter), to handle the different camera trigger modes, to access optimally the camera internal memory buffer, to replay an acquired sequence, to select the relevant frames, and eventually to export the selected ones.
The high speed DHM® system enables novel research among others in the fields of energy harvesting, impact analysis, fluid interfaces, transients, stress analysis, evaporation, drying, absorption, desorption, and dissolution phenomena, etc.
