Optical system and image enlargement device

An optical system, comprising:

• a display;
• and
• an optical component disposed between the display and a viewing position, the optical component comprising:
• a first reflective element for receiving an incident light emitted from the display;
• and
• a second reflective element disposed on a reflected light path of the first reflective element, configured to receive the incident light reflected by the first reflective element and reflect the reflected incident light to a viewing position, and the first reflective element and/or the second reflective element having a function of concentrating light;
• wherein light emitted from a center point of the display is sequentially relayed by a first incident point of the first reflective element and a second incident point of the second reflective element and then reaches the viewing position, the first incident point is at a position different from that of a center point of the first reflective element, the second incident point is at a position different from that of a center point of the second reflective element, an optical path of the center point of the display, the first incident point, and the second incident point is an optical axis of the optical system, and the display, the first reflective element and the second reflective element are disposed along the optical axis,
• wherein an out-light surface of the display is perpendicular to a horizontal line passing through the viewing position.

An image enlargement device, comprising:

• a left eye module corresponding to a left eye;
• a right eye module corresponding to a right eye, wherein each of the left eye module and the right eye module comprises:
• a first reflective module is composed of a plurality of first reflective mirrors, adjacent edges of the plurality of first reflective mirrors are bonded together, and reflective surfaces of the plurality of first reflective mirrors constitute a reflective surface of the first reflective module;
• a second reflective module is composed of the plurality of second reflective mirrors, and reflective surfaces of the plurality of second reflective mirrors constitute a reflective surface of the second reflective module;
• the second reflective module is disposed on a reflected light path of the first reflective module, the second reflective module is configured to reflect a light reflected by the first reflective module to a viewing position of the corresponding eye.
