Claim 11:
12. The projection system according to claim 11, wherein the light deflecting device is a square flat plate, and the one or more illumination sub-beams transmit through the light deflecting device to irradiate the plurality of micromirror units;
wherein the light deflecting device has four position states corresponding to the four sections of the micromirror unit in one-to-one correspondence, and the light deflecting device is configured to deflect from an initial position state of the four position states along a first deflection axis, a second deflection axis, and a third deflection axis to a second position state, a third position state, and a fourth position state of the four position states, respectively, to shift the illumination sub-beam to the four sections of the micromirror unit; and
wherein the light deflecting device comprises a first side, a second side, a third side, and a fourth side that are connected end-to-end to form the square flat plate; and the first deflection axis is parallel to the first side or the third side; the second deflection axis is parallel to the second side or the fourth side; the first side and the second side intersect at a first intersection side, the third side and the fourth side intersect at a second intersection side, and the third deflection axis is parallel to a line connecting the first intersection side to the second intersection side.
