Converts a monocular camera into a binocular stereo camera using a reflective optical arrangement, for an AR-capable display device.
An optical system, suitable for use within an augmented reality (AR)-capable display device, comprises a camera and an optical arrangement configured to acquire stereoscopic imagery of an object using the camera. The optical arrangement comprises a first reflective element arranged along a first optical path and defining a first convex surface configured to reflect first light received from the object as first reflected light, wherein at least a first portion of the first reflected light is directed onto a camera focal plane. The optical arrangement further comprises a second reflective element having a predefined disposition relative to the first reflective element. The second reflective element is arranged along a second optical path and defines a second convex surface configured to reflect second light received from the object as second reflected light, wherein at least a second portion of the second reflected light is directed onto the camera focal plane.
