| Popis: | In this paper, based on the spatially and temporally resolved intensity and phase evaluation device: full information from a single hologram (STRIPED FISH), an improved single-frame full spatiotemporal field distribution measurement method is proposed. In our scheme, between diffractive optical element (DOE) and band-pass filter (BPF), and between BPF and the CCD camera, digital micromirror devices (DMD) are introduced to perfect the setup. Compared with the STRIPED FISH, our improved scheme can simultaneously improve the frame rate and maximize the utilization efficiency of the SBP of CCD. And simulation is carried out to demonstrate the process of the implementation, which confirmed the feasibility of the proposal. |
