We propose a simple single-shot spatiotemporal measurement technique called coherent modulation imaging for the spatio-spectrum (CMISS), which reconstructs full three-dimensional high-resolution characteristics of ultrashort pulses based on frequency-space division and imaging. demonstrated it experimentally by measuring amplitude phase single pulse with spatial resolution 44 µm accuracy 0.04 rad. CMISS has good potential high-power ultrashort-pulse laser facilities can measure even spatiotemporally complicated important applications.
