Abstract
The present application relates to the technical field of ultrafast imaging, and provides an ultrafast framing optical imaging device with a real-time high spatial resolution. The optical imaging device includes an ultrashort pulse laser system with a magnitude of femtosecond, a frequency multiplier, a wavelength splitter, a continuous illumination laser, a sampling plate, a calibration camera, a first imaging record module, and a second imaging record module. The present application mainly utilizes continuous light illumination ultrafast events and non-collinear light parameter amplifying technology that uses ultrashort pulse laser to pump/sample events at different moments, and adopts a plurality of CCD cameras to receive corresponding idle light images simultaneously and respectively and thereby realize ultrafast framing optical imaging with a high time resolution.
