HEADS-UP DISPLAY WITH INTEGRATED DISPLAY AND IMAGING SYSTEM

摘要

Embodiments of an apparatus comprising a light guide including a proximal end, a distal end, a display positioned near the proximal end, an ocular measurement camera positioned at or near the proximal end to image ocular measurement radiation, a proximal optical element positioned in the light guide near the proximal end and a distal optical element positioned in the light guide near the distal end. The proximal optical element is optically coupled to the display, the ocular measurement camera and the distal optical element and the distal optical element is optically coupled to the proximal optical element, the ambient input region and an input/output optical element. Other embodiments are disclosed and claimed.

1. An apparatus comprising:
a light guide including a proximal end, a distal end, a front surface and a back surface spaced apart from the front surface, an ambient input region on the front surface near the distal end, and an input/output region on the back surface near the distal end; a display positioned near the proximal end; a camera positioned at or near the proximal end to image ocular measurement radiation; a proximal optical element positioned in the light guide near the proximal end and a distal optical element positioned in the light guide near the distal end, wherein the proximal optical element is optically coupled to the display, the camera and the distal optical element such that it directs display light to the distal optical element and directs ocular measurement radiation received from the distal optical element to the camera, and wherein the distal optical element is optically coupled to the proximal optical element, the ambient input region and the input/output region such that it directs display light and ocular measurement radiation to the input/output region and directs ocular measurement radiation from the input/output region to the proximal optical element; and an input/output optical element optically coupled to the input/output region, the input/output optical element having optical power at the wavelength of the ocular measurement radiation.
