Polymeric, birefringent reflective polarizers have been used to produce compact, mid-field-of-view eyepieces and wide field-of-view optics for virtual reality (VR) head-mounted displays using the “pancake” lens configuration. Multiple configurati

Over the past decade, 3M has developed a number of mobile projectors, with a goal towards providing the world’s smallest, most efficient projection systems. Compact size and efficiency are required characteristics for projection systems used in mob

In this paper, we study and characterize the cracking behavior of a sol-gel-derived amorphous silica film on a InP substrate. The sol-gel silica films are deposited by spin-coating and rapid thermal processing (RTP). It is observed that the volatilit

Eyepieces are a part of visual optical systems. Because of their wide field of view and long eye-relief, it is difficult to further improve the existing eyepieces using all-refractive surfaces. Since diffractive elements demonstrate unique characteri

In both design and fabrication, diffractive optical elements (DOEs) are more flexible and powerful than traditional refractive/reflective optical elements, hence an optical system with one or more diffractive elements may provide better optical perfo

In planar diffractive imaging system, extra-axial imaging elements are frequently used. Since the elements have large off-axial aberrations such as coma, astigmatism, field curvature and distortion, it seems a little difficult to design a practical a

Compared to the holographic elements, the binary optical element (BOE) is more flexible and powerful in its design, functionality and fabrication. Better optical performance, with the advantages of compactness, lightweight, and low cost, is possible

The study of planar imaging system is an interesting topic because its compact structure and lightweight are consistent with the trend of production miniaturization. This paper presents our study of designing and fabricating planar imaging elements.

A novel planar-binary optical see-through visor, in which three binary optical elements, namely two couplers and one compensator, are designed to be fabricated on a planar glass slide substrate, is presented in this paper. One binary focusing coupler
