Abstract: A HMD system including a visor mounted on a head of a user. The visor includes adjustable light transmission layer activated by activation radiation of at least a visible activation waveband and an Ultra Violet (UV) activation waveband. The visor defines a Line Of sight (LOS) projecting from a point on the visor and further defines a Field Of View (FOV) projecting from at least a section of the visor that surrounds the point on the visor. The visor is configured to admit an outside scene image. The HMD system further includes a luminosity sensor configured to detect luminosity within the FOV and a UV activation radiation source configured to selectively irradiate at least a portion of the visor with activation UV light included in the UV activation waveband according to luminosity detected by the luminosity sensor, thereby activating the adjustable light transmission layer.

Abstract: An eyepiece suitable for a night vision device, having an optical combiner for injecting a synthetic image onto the scene and having a single optical correction mechanism is provided herein. The eyepiece may include an observer-side lens; an objective-side lens; a diopter adjustment knob configured to set a distance between the observer-side lens and the objective-side lens; and an optical combiner located between the objective-side lens and the objective-side lens, wherein the optical combiner reflects towards the observer-side lens, the synthetic image transmitted from outside the eyepiece and transfers towards the observer-side lens, a scene image coming from an objecting lens of the night vision device and passing through the objective side lens, and wherein the diopter adjustment knob serves as a single setting mechanism which simultaneously sets a diopter of the observer and a focal depth of the display source image.

Abstract: Method and system for enhancing visual perception of augmented reality presentation. The location and line-of-sight (LOS) of a user wearing a see-through head-mounted display (HMD) is detected. A future background environment to be viewed by the user through the HMD is predicted based on at least the detected location and detected LOS. At least one color-attribute of the future background environment at a background location corresponding to a user LOS is predicted. The predicted color-attribute is compared with at least one color-attribute of an intended foreground supplementary image to be projected on the HMD overlaid onto the future background environment at the background location. When an incompatibility condition is detected, at least one visual parameter of the supplementary image is adjusted to minimize the incompatibility condition, and the supplementary image is projected on the HMD at the background location with the adjusted visual parameter.

Abstract: Optical systems and methods are provided, which combine see-through view of the real world and display source images using a conical optical combiner cut to have flat surfaces normal to the viewer line of sight. The conical shape minimizes interferences in the view of the real world as the edges of the optical combiner are tangent to the viewer vision field of view and the inner part of the optical combiner is semitransparent. Additionally, the optical system comprises a beam splitter, a shutter(s) for attenuating or blocking the see-through path and may employ polarizing element to improve the contrast between the scene observation and the projected display and thus enabling selective viewing of either. The system may also be configured to enable diopter adjustment and virtual display distance adjustments.
