Abstract
Embodiments of this specification provide an optical apparatus and a head-mounted device. The optical apparatus may include an image assembly, a first optical assembly, a second optical assembly, and a third optical assembly, the image assembly is configured to emit image light. The image assembly, the first optical assembly, the second optical assembly, and the third optical assembly are configured to enable that the image light is transmitted through the first optical assembly to the second optical assembly, then reflected through the second optical assembly to the third optical assembly, then reflected through the third optical assembly back to the second optical assembly and transmitted through the second optical assembly into a user's eye. The second optical assembly is configured to block interference light incident on the second optical assembly from entering the user's eye. The third optical assembly is configured to block the image light from being transmitted through the third optical assembly to enter an external environment.
