Abstract
A pair of projection glasses, a projection temple structure, and a modularized optical engine are provided. The pair of projection glasses includes a frame and a projection temple structure that is detachably fastened to the frame. The projection temple structure includes a temple and a modularized optical engine that is embedded in the temple. The modularized optical engine includes a light emitting mechanism, a projection mechanism spaced apart from the light emitting mechanism, and a connection mechanism that optically and electrically connects the light emitting mechanism and the projection mechanism. The connection mechanism is configured to transmit light and image signal from the light emitting mechanism to the projection mechanism, so that the projection mechanism can project an image light.
