摘要： A waveguide display system (1400), comprising a waveguide (1442) having a first surface (1421) and a second surface (1422), the waveguide(1442) including an incoupling diffractive optical element (1446), DOE, and an outcoupling DOE (1448); a point light source (1415) configured to provide a divergent input light beam (1411); a scanning mirror (1420) adjacent to the second surface (1422), configured to receive the divergent input light beam (1411) through the waveguide (1442) and to provide a divergent reflected light beam (1455); a collimating scanning optical element (1430) adjacent to the first surface (1421), configured to receive the divergent reflected light beam (1455) through the incoupling DOE (1446) and to produce a collimated reflected light beam (1460); wherein the incoupling DOE (1446) is configured to prevent the divergent reflected light beam (1455) from the scanning mirror (1420) from propagating to the outcoupling DOE (1448) through total internal reflection TIR; and cause the collimated reflected light beam (1460) to propagate to the outcoupling DOE (1448) through TIR.

摘要： A method of depositing a variable thickness material, the method comprising providing (1205) a substrate comprising a uniform diffractive structure including a plurality of diffractive elements; providing (1210) a shadow mask having a first region with a first aperture dimension to aperture periodicity ratio and a second region with a second aperture dimension to aperture periodicity ratio less than the first aperture dimension to aperture periodicity ratio; positioning (1215) the shadow mask adjacent the substrate; and performing (1220) a deposition process on the substrate to deposit the variable thickness material, wherein a layer thickness adjacent the first region is greater than a layer thickness adjacent the second region.

摘要： Embodiments of the present disclosure are directed to an optical device, such as an eyepiece, including multiple layers of waveguides. The optical device can include an edge sealant for reducing light contamination, a lamination dam to restrict the wicking of the edge sealant between layers of the optical device, and venting gap(s) in the sealant and dam to allow air flow between the exterior and interior of the eyepiece. The gap(s) allow outgassing from the interior of the eyepiece of unreacted polymer and/or accumulated moisture, to prevent defect accumulation caused by chemical reaction of outgassed chemicals with the (e.g., ionic, acidic, etc.) surface of the eyepiece layers. The gap(s) also prevent pressure differences which may physically deform the eyepiece over time.

摘要： An endovascular shunt implantation system, comprising a guide member (320) having a distal portion configured for being deployed in an inferior petrosal sinus (IPS) of a patient; a delivery catheter (3304) movably coupled to the guide member (320), wherein a distal end of the delivery catheter comprises or is otherwise coupled to a tissue penetrating element (3350), such that the delivery catheter (3304) and tissue penetrating element (3350) are translatable relative to the distal portion of the guide member (302) within the IPS of the patient, the delivery catheter (3304) comprising a lumen (3341) in communication with an opening in the tissue penetrating element (3350); and a guard member (4000) at least partially disposed over, and movable relative to, the tissue penetrating element (3350), the guard member (4000) having an open distal end portion including an inner surface feature (4030) configured to deflect the tissue penetrating element (3350) away from the guide member (320) when the tissue penetrating element (3350) is translated distally relative to the guard member (4000) or when the guard member (4000) is withdrawn proximally relative to the tissue penetrating element (3350).
