A mammography system using a tissue exposure control relying on estimates of the thickness of the compressed and immobilized breast and of breast density to automatically derive one or more technic factors. The system further uses a tomosynthesis arrangement that maintains the focus of an anti-scatter grid on the x-ray source and also maintains the field of view of the x-ray receptor. Finally, the system finds an outline that forms a reduced field of view that still encompasses the breast in the image, and uses for further processing, transmission or archival storage the data within said reduced field of view.

An augmented reality (AR) device is described with a display system configured to adjust an apparent distance between a user of the AR device and virtual content presented by the AR device. The AR device includes a first tunable lens that change shape in order to affect the position of the virtual content. Distortion of real-world content on account of the changes made to the first tunable lens is prevented by a second tunable lens that changes shape to stay substantially complementary to the optical configuration of the first tunable lens. In this way, the virtual content can be positioned at almost any distance relative to the user without degrading the view of the outside world or adding extensive bulk to the AR device. The augmented reality device can also include tunable lenses for expanding a field of view of the augmented reality device.

The present invention defines a quantitative measure for expressing the spatial (geometric) accuracy of a single optical geo-referenced image. Further, a quality control (QC) method for assessing that measure is developed. The assessment is done on individual images (not stereo models), namely, an image of interest is compared with automatically selected image from a geo-referenced image database of known spatial accuracy. The selection is based on the developed selection criterion entitled “generalized proximity criterion” (GPC). The assessment is done by computation of spatial dissimilarity between N pairs of line-of-sight rays emanating from conjugate pixels on the two images. This innovation is sought to be employed in any optical system (stills, video, push-broom, etc), but its primary application is aimed at validating photogrammetric triangulation blocks that are based on small (<10 MPixels) and medium (<50 MPixels) collection systems of narrow and dynamic field of view together with certifying the respective collection systems.
