Claim 1:
2. The ultrafast photographing apparatus based on polarization-time mapping according to claim 1, wherein a femtosecond laser pulse generated by the femtosecond laser system (101) of the active illumination system (100) has a pulse duration of 60 fs, a wavelength range from 780 nm to 820 nm, a spectral bandwidth of 40 nm, a repetition frequency of 100 Hz, and a single pulse energy of at least 3 mJ; the pulse stretcher (102) is able to cover a chirping range of the femtosecond laser pulse from 2 ps to 200 ps; and the scattering medium (105) is an engineering scatterer and is configured to perform decoherence on the femtosecond laser pulse.
