Title: The Innovative Contributions of Yi Qin

Introduction

Yi Qin is a prominent inventor based in Mountain View, CA, known for his significant contributions to augmented reality technology. With a total of 14 patents to his name, he has made remarkable strides in enhancing user experiences through innovative display technologies.

Latest Patents

Among his latest patents is the "Polarization-dependent augmented reality display." This device provides light for augmented reality vision by utilizing a display that emits light toward a beam splitter. The beam splitter reflects light from the display toward a polarization-dependent lens, allowing world scene light to pass through to the lens. This innovative design directs both display light and world scene light toward a non-polarization-dependent lens positioned at the eye-ward side of the polarization-dependent lens.

Another notable patent is the "Head mounted display with lightguide and multiple combiners." This head-mounted display (HMD) offers multiple fields of view of a single micro-display by time-multiplexing the provision of light of different polarizations. The HMD includes a micro-display, a lightguide, and several combiners coupled to the lightguide, each configured to combine light of a different polarization. A polarizer switch is included in a filter stack for the lightguide, allowing for alternating provision of light having P-polarization and S-polarization, respectively.
