Abstract: Provided are an optical waveguide and an optical waveguide sight, relating to optics technical field. In the optical waveguide sight, a light source and a collimating element are sequentially arranged along an in-coupling channel of a non-pupil-expansion optical waveguide. The collimating element is configured to collimate light beam emitted from light source, forming first parallel light beam, which is transmitted to the in-coupling region. The non-pupil-expansion optical waveguide is configured to redirect and transmit the first parallel light beam to an out-coupling region thereof to form second parallel light beam that is emitted to human eyes. The non-pupil-expansion optical waveguide enables efficient transmission and expansion of optical path with compact structure, broadening effective observation field of view while maintaining small footprint.
