Example Embodiment
[0033] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0034] figure 1 A schematic diagram of a head-mounted optical system according to an embodiment of the present invention is shown. Such as figure 1 As shown, the head-mounted optical system adopts an inverted chasing light path design, and includes an aperture 110, an eyepiece lens 120, and a micro-display 130.
[0035] The eyepiece lens 120 includes four lenses, which are in turn against the incident direction of light:
[0036] The first positive lens 121 has a first surface S1 that is flat and a second surface S2 that is convex toward the light incident side; the second positive lens 122 has a third surface S3 that is convex toward the light emitting side and a third surface S3 that is convex toward the light incident side. The fourth surface...
