The detector includes a detector pattern for detecting an image of the object. The lens arrangement is between the beam splitter and the object and includes: a light source that generates the light beam, and a device configured to switch a direction of polarization of the light beam to generate a changing projector pattern.

Abstract: A visualization device allows a user to be immersed in visual content by projecting the visual content to the user. A projection element is positioned such that visual content projected from the projection element is reflected off of a mirror, which is angled such that the reflected projection is reflected onto a lens doublet. The lens doublet is angled such that the visual content projection reflected onto the lens doublet is partially reflected toward the user. In addition, an electrochromic slab can be controlled to allow configurable amounts of ambient light into the visualization device. If the electrochromic slab is configured such that no ambient light is allowed into the visualization device, the user is only able to see the visual content projected by the display device. The electrochromic slab can also be configured to allow some or all ambient light to travel into the visualization device.

Abstract: Methods and systems for the super-resolution imaging can make visible strongly subwavelength feature sizes (even below 100 nm) in the optical images of biomedical or any nanoscale structures. The main application of the proposed methods and systems is related to label-free imaging where biological or other objects are not stained with fluorescent dye molecules or with fluorophores. This label-free microscopy is more challenging as compared to fluorescent microscopy because of the poor optical contrast of images of objects with subwavelength dimensions. However, these methods and systems are also applicable to fluorescent imaging. Their use is extremely simple, and it is based on application of the microspheres or microcylinders or, alternatively, elastomeric slabs with embedded microspheres or microcylinders to the objects which are deposited on the surfaces covered with thin metallic layers or metallic nanostructures.
