Fig. 1. SV-CUP’s configuration and principle. (a) System configuration of SV-CUP: M1 and M2, mirrors; ED, engineered diffuser; DS, dynamic scene; CL, camera lens; BS1 and BS2, beam splitters (reflection/transmission: 50/50); F1 and F2, filters; G, diffraction grating; L1 and L2, lenses; DMD, digital micromirror device; CMOS, complementary metal-oxide semiconductor camera; and SC1 and SC2, streak cameras. (b) Working principle of SV-CUP: C, spatial encoding operator; T, temporal shearing operator; K, spatial-temporal integration operator; S, spectral shearing operator; and M, spatial–temporal–spectral integration operator.
