Abstract

Pulsed digital holography, which combines femtosecond pulsed laser and digital holography, is a novel technology for detecting ultrafast transient processes in real-time. Pulsed digital holography can obtain a series of amplitude and phase information of the ultrafast process in one shot at the femtosecond or picosecond order, and comprehensively characterize the whole picture of the ultrafast process. However, the system of pulsed digital holography currently has the defects of complexing, poor stability, small number of pulse frames, and low utilization of space bandwidth, which seriously limits practical applications. In this work, a real-time detection system is designed for ultrafast transient processes, which has the property of high stability, femtosecond or picosecond time order resolution, and adjustable pulse frames. The pulsed lasers are used instead of traditional continuous lasers. The proposed system design provides a competitive approach to ultrafast transient imaging.
