Optical module and electronic device

An optical module, comprising:

• a beam splitting assembly configured to divide an incident light into a first light beam and a second light beam that propagate in different directions;
• a first dimming assembly and a second dimming assembly, wherein the first dimming assembly is located on a light path of the first light beam, the second dimming assembly is located on a light path of the second light beam, the first dimming assembly and the second dimming assembly adjust propagation directions of the first light beam and the second light beam respectively so that the light path of the first light beam and the light path of the second light beam have an intersection position;
• and
• a beam combining assembly located at the intersection position so that the first light beam and the second light beam entering the beam combining assembly exit concurrently along a same direction
• wherein the beam splitting assembly is a glued prism formed by gluing four isosceles triangular prisms, the glued prism has a light incidence surface and two light exit surfaces, the incident light enters from the light incidence surface, and the first light beam and the second light beam exit from the two light exit surfaces respectively.
