Holographic display system

An augmented reality (AR) holographic display system disposed in a head-mounted display device, the system comprising:

• a laser light source that emits coherent light;
• a reflector that optically receives the coherent light and generates reflection light;
• a lateral displacement beam splitter that optically receives the reflection light and generates first reference light and second reference light;
• a first spatial light modulator (SLM) and a second SLM that optically receive the first reference light and the second reference light respectively, and construct first phase-only function (POF) light and second POF light respectively;
• a first reflector disposed between the lateral displacement beam splitter and the first SLM;
• a second reflector disposed between the lateral displacement beam splitter and the second SLM;
• a first beam splitter and a second beam splitter that optically receive the first POF light and the second POF light respectively, and generate first split light and second split light respectively;
• and
• a first polarizer disposed between the first SLM and the first beam splitter, a second polarizer disposed between the second SLM and the second beam splitter, a third polarizer disposed between the first reflector and the first SLM, and a fourth polarizer disposed between the second reflector and the second SLM.
