This optical architecture can make use of one, two, or three freeform surfaces. Our initial prototype uses a single freeform surface along with a sphere and a at surface to simplify manufacturing complexity. There are two key contributions in this paper that to our knowledge have not been achieved previously: 1) the design of a thin, 4 mm to 1 mm gradient thickness, curved freeform lightguide (nearly 4x thinner than the original freeform prism), and 2) lightguide fabrication utilizing ophthalmic machines. This particular optical design makes combined use of total internal reflections and partial reflections. The advantages of this optical architecture include the curved optical surfaces that eliminate the optical collimator requirement in at lightguides, a relatively large eyebox, and a manufacturing approach that reuses the standard ophthalmic process for fabri...

Based on knowing the time and location of the written notes on ordinary paper, we are able to create a novel method for capturing and accessing the lecture content in real-time (this doesn't

Typical optical surfaces implemented in raytrace codes today are functions mapping two dimensional vectors to real numbers. The majority of optical designs to date have relied on conic sections and polynomials as the functions of choice. The choice of conic sections is justified since

Ideally, one would wish for such capability to exist without the need to wear any view-aided device. However, unless a display system could be created in space, anywhere and anytime, a simple solution is to wear the display. We review in this paper
