Fig. 2: The maximum occupation of sub-ROI testing, and the framerate demonstration with QXGA and SXGA series of SLM under 2 Angles 3 Phases or 3 Angles 3 Phases SIM excitation.

a QXGA for maximum occupation test, the max sub-ROIs are 192 pixels (H)×676 pixels (W) in 0.2 ms 1-bit balance pattern exposure when the frame opens 400 pixels (H) × 2048 pixels (W), and b 236 pixels (H)×676 pixels (W) in 0.4 ms 1-bit balance mode when the frame opens 496 pixels (H)×2048 pixels (W). The maximum in SXGA (c) can be around 234 pixels (H)×676 pixels (W) when the frame is 484 pixels (H)×2048 pixels (W) in 0.2 ms, and d 296 pixels (H)×676 pixels (W) in 0.4 ms displaying when the frame opens 608 pixels (H)×2048 pixels (W). In the framerate demonstration, the correct angles are illustrated by FFT hot map containing counterpart of ±1 order surefire directions circled with white, which are consistent with the direction of red arrows on top-right part of each sub-ROI. The fringe phases are corrected by checking successful reconstruction. c Sub-ROIs’ size in SXGA group is only for pattern displaying demonstration. c the sub-ROIs are 192 pixels (H)×400 pixels (W) in 0.2 ms 1-bit balance displaying mode when the frame opens 484 pixels (H)×2048 pixels (W), and d 260 pixels (H)×540 pixels (W) in 0.4 ms 1-bit balance mode when the frame opens 608 pixels (H)×2048 pixels (W). Using the QXGA, 0.2 ms and 0.4 ms PAR-SIM framerate are 256 Hz and 204 Hz, respectively, when under 2 Angles 3 Phases SIM mode; and corresponding to 171 Hz and 136 Hz under 3 Angles 3 Phases SIM. Meanwhile using SXGA, 0.2 ms and 0.4 ms PAR-SIM framerate are 209 Hz and 167 Hz, respectively, when under 2 Angles 3 Phases mode; and with respect to 140 Hz and 112 Hz under 3 Angles 3 Phases mode. All the framerates from the whole frame above almost match their respective theoretical opened row numbers on the sensor because of the flexible synchronization margin mentioned above.
