Abstract: An apparatus reduces optical damage on an optical element that interacts with a light beam. The apparatus includes: an optical system configured to interact with a light beam to perform a modification to one or more aspects of the light beam, an alignment system, and an actuator. The optical system comprises at least one optical element having a surface configured to interact with the light beam, the surface being continuous and non-diffuse. The alignment system is configured to align the light beam relative to the optical element surface so that the light beam interacts with the optical element while the light beam is traveling at a first beam direction relative to the surface of the optical element and the light beam is outputted from the optical element along a second beam direction relative to the surface of the optical element after the light beam and optical element have interacted.

Abstract: An augmented reality head worn device comprising a curve combiner transparent to visible light and reflective in an selected infrared frequency range, a scanning light source defining a field of view, a holographic optical element adapted to provide pupil expansion to create an eye-box, and at least one projection system for providing high acuity at or near a center of the field of view.

Abstract: The invention provides an optical device for displaying one or more images on a picture tube so as to be viewable from the anterior end of the device. The optical device can be used to display abstract or non-abstract subject matter. The optical device includes a picture tube having one or more images to be displayed by the device and an imaging assembly housed in a cavity formed by lateral sides of the picture tube, the imaging assembly having a reflecting surface that reflects the one or more images on the picture tube so as to be viewable from the anterior end of the device.

Abstract: An actuation system (44) for controlling a first door (38) and a second door (40) includes a first actuator (72) having a first interior passage (74) and a second actuator (76) in line with the first actuator (72). A first shaft (82) extends from the first actuator (72) and has a second interior passage (86). A second shaft (88) extends from the second actuator (76) and is directed through the first and second interior passages (74, 86) to exit from the first shaft (82). The first shaft (82) is in communication with the first door (38), and the first actuator (72) drives the first shaft (82) to move the first door (38). The second shaft (88) is in communication with the second door (40), and the second actuator (76) drives the second shaft (88) to move the second door (40) independent from movement of the first door (38).
