Abstract: The optical machine module includes a light emitting module and a modulation module. The light emitting module includes a light source configured to emit linearly polarized light. The modulation module includes a modulation component. The modulation component includes a light-combining prism and a liquid crystal on silicon (LCOS) modulator. The light-combining prism includes four rectangular prisms. The light-combining prism has four sides and four intersection planes formed by the four rectangular prisms. The LCOS modulator includes a first LCOS modulator, a second LCOS modulator, and a third LCOS modulator. The first LCOS modulator, the second LCOS modulator, and the third LCOS modulator are respectively disposed on light emitting sides of three different sides. At least two of the four intersection planes are configured to split light. At least two of the four intersection planes are configured to combine light.
