Abstract

A spatial light modulator and a projection system are provided. The spatial light modulator includes a substrate layer, a first electrode layer, a first metasurface layer, a phase change material layer, a second electrode layer, and a first flat layer. The first electrode layer and the second electrode layer are respectively disposed on opposite sides of the substrate layer and the first flat layer that are parallel to each other, and the first metasurface layer and the phase change material layer are disposed between the first electrode layer and the second electrode layer. The first metasurface layer includes at least two metasurface units that are sequentially arranged, and a resonance frequency of each metasurface unit corresponds to a preset incident optical wavelength of each metasurface unit. The spatial light modulator performs phase modulation on incident light through the first metasurface layer and the phase change material layer.
