A transparent thin film electroluminescent display device includes a first transparent thin film electroluminescent display having a substrate and a first active layer capable of emitting a spectrum of light in a wavelength of visible light. The transparent thin film electroluminescent display device further includes a second transparent thin film electroluminescent display having a substrate and a second active layer, the first and second transparent thin film electroluminescent displays being arranged in a superposed manner such that the first and second active layers are spaced apart from each other for forming the transparent thin film electroluminescent display device with a superposed structure.

A system, method, and device for configuring an optical aiming device for ballistic drop compensation (BDC). The optical aiming device can include a housing with a reticle pane defining a reticle display field viewable by a user and indicating a zero point, the housing further including a plurality of axially spaced lenses and defining an optical path therethrough. In various embodiments the system includes a display device configured to project an image generated from a display, a processor, and a non-transitory computer readable storage medium. The computer readable data storage medium can include instructions executable by the processor to receive a first set of ballistics input data indicating a first type of ammunition, determine a BDC pattern including at least two holdover marks corresponding to at least two ranges for the first type of ammunition, and project the BDC pattern onto the reticle display field.

Fiducial patterns that produce 2D Barker code-like diffraction patterns at a camera sensor are etched or otherwise provided on a cover glass in front of a camera. 2D Barker code kernels, when cross-correlated with the diffraction patterns captured in images by the camera, provide sharp cross-correlation peaks. Misalignment of the cover glass with respect to the camera can be derived by detecting shifts in the location of the detected peaks with respect to calibrated locations. Devices that include multiple cameras behind a cover glass with one or more fiducials on the cover glass in front of each camera are also described. The diffraction patterns caused by the fiducials at the various cameras may be analyzed to detect movement or distortion of the cover glass in multiple degrees of freedom.

A duration of time in which an individual observed a region can be determined. An image can be received. The image can include an indication of a point of gaze of the individual at a production time of the image. The image can include a visual fiducial marker, which can be disposed at a position in the image and can include a visual symbol. The visual symbol can be associated with data that define the region. The region can have a shape and a size and can be disposed a displacement in a direction from a position of the visual fiducial marker. Using the visual symbol, a location of an edge of the region can be determined. The indication of the point of gaze can be determined to be within the region. The production time of the image can be determined to be within the duration of time.

A digital booster for an optical system includes an image acquisition unit. The image acquisition unit is configured to acquire an image frame from a non-magnified optic. The image frame includes an aiming reticle imposed by the non-magnified optic. The digital booster includes a display and a processor. The processor is configured to locate the aiming reticle on the image frame, select a sub-frame of the image frame with an aspect ratio that is centered on the aiming reticle of the image frame, perform image inversion and rescaling of the sub-frame, and transmit the sub-frame to the display.

The present approach relates generally to image-based approaches for detecting deviations from a linear movement when scanning a surface. More particularly, the approach relates to the use of linear fiducials to detect, in real-time, deviations from a linear scan path during operation of a scanning imaging system. Such linear fiducials may include both sample sites and blank regions or sites or, in certain embodiments, may utilize elongated sample sites (e.g., linear features) within the linear fiducial.
