See full text

An optical system is configured to form an enlarged image of a display surface of an image display element and includes, in order from a side of an exit pupil to a side of the display surface, a first half-transmissive reflective surface and a second half-transmissive reflective surface. The optical system has a first optical path on which light from the display surface transmits through the second half-transmissive reflective surface, is reflected by the first half-transmissive reflective surface, is reflected by the second half-transmissive reflective surface, transmits through the first half-transmissive reflective surface, and is guided to the exit pupil, and a second optical path on which light from the side of the exit pupil transmits through the first half-transmissive reflective surface, transmits through the second half-transmissive reflective surface, and is guided to an image sensor.
