1. An optical module, comprising:
a partial reflector, receiving circularly polarized light or elliptically polarized light, wherein part of the circularly polarized light or elliptically polarized light is reflected and part of the circularly polarized light or elliptically polarized light transmits through the partial reflector;
a second phase delay unit, located downstream of an optical path of the partial reflector so as to receive and modulate the transmitting circularly polarized light or elliptically polarized light before emission; and
a polarized beam splitter, disposed downstream of an optical path of the second phase delay unit, the polarized beam splitter having a light transmission axis,
wherein the optical module further comprises a second phase compensation unit located between the second phase delay unit and the polarized beam splitter, and wherein an optical axis of the second phase compensation unit is located in a plane orthogonal to the light transmission axis of the polarized beam splitter, or in a plane orthogonal to a light reflection axis of the polarized beam splitter.
