The light guide component includes an input surface oriented to receive the display light into the light guide component, an eye-ward facing surface having a reflection portion and a viewing portion, a folding surface oriented to reflect the display light received through the input surface to the reflection portion of the eye-ward facing surface, and a first interface surface oriented to receive the display light reflected from the reflection portion of the eye-ward facing surface. A partially reflective layer is disposed on the first interface surface in the viewing region to reflect the display light along the eye-ward direction through viewing portion of the eye-ward facing surface.

摘要： An eyepiece includes a display module for providing display light, a concave end reflector, and a viewing region including a partially reflective surface to redirect at least a portion of the display light out of an eye-ward side of the eyepiece along an emission path. The partially reflective surface is obliquely angled with an offset from 45 degrees relative to the eye-ward side to cause the emission path to have a first oblique angle in a horizontal dimension relative to a first normal vector of the eye-ward side. The concave end reflector is tilted such that a second normal vector from a center point of the concave end reflector is obliquely angled relative to a top or bottom surface of the eyepiece to cause the emission path to have a second oblique angle in a vertical dimension relative to the first normal vector of the eye-ward side.

The optical combiner has an eye-ward side and an external scene side and includes a partially reflective diffraction grating that is at least partially reflective to image light incident through the eye-ward side and at least partially transmissive to external scene light incident through the external scene side. A first mount is positioned to hold the image lens in an optical path of the image light to apply a first corrective prescription to the image light. A second mount is positioned to hold an external scene lens over the external scene side of the optical combiner to apply a second corrective prescription to the external scene light. The optical combiner combines the image light with the scene light to form a combined image that is corrected according to the first and second corrective prescriptions.

摘要： A passive infrared motion detection sensor that includes a Fresnel focusing arrangement that creates at least a first infrared sensing region, a second infrared sensing region, and a third infrared sensing region, in which target detection in one or more infrared sensing regions is weighted to be distinguishable from target detection in remaining infrared sensing regions. The Fresnel focusing arrangement creates the weighted infrared sensing regions using a lenslet region, an optically opaque region and a plurality of extruded cylindrical lenslets that extend across a portion of both the lenslet region and the optically opaque region. The signal detection in at least the second weighted infrared sensing region, for example, an infrared sensing range between 6 and 10 feet, is weighted to easily distinguish between a pet within the second infrared sensing range and a person at any infrared sensing range.

摘要： An eyepiece body of an eyepiece includes an input lens positioned to couple display light into the eyepiece body along a forward propagation path, a concave end reflector disposed at an opposite end of the eyepiece body from the input lens to reflect the display light back along a reverse propagation path, and a viewing region including a partially reflective surface that redirects at least a portion of the display light traveling along the reverse propagation path out of an eye-ward side of the eyepiece body along an emission path. The partially reflective surface is obliquely angled relative to the eye-ward side and the concave end reflector is titled relative to a top or bottom surface of the eyepiece body to collectively cause the emission path of the display light to be oblique to a normal vector of the eye-ward side in two orthogonal dimensions.
