Abstract: Image calibration is performed for an image display apparatus. A known image is scanned with the image scanning apparatus using a first scanning resolution of the image scanning apparatus to obtain a scanned known image. The scanned known image is displayed on the image display apparatus using the first scanning resolution as a displayed known image. The image display apparatus is adjusted such that the displayed known image is an exact replica of the known image.

Abstract: An assembly for mounting a flexible display sheet to a structure includes an adjustment bracket having a first end and an opposing second end, the display sheet being secured to the first end of the adjustment bracket. A brace is rigidly attached to the structure, the brace having an opening extending therethrough. A coupling pin has a first end and an opposing second end, the first end of the coupling pin being mounted to the second end of the adjustment bracket, the second end of the coupling pin extending through the opening on the brace. An advancing nut is threadedly mounted on the second end of the coupling pin, the advancing nut being configured to bias against the brace so as to advance the coupling pin through the opening on the brace as the advancing nut is threaded onto the coupling pin.

Abstract: An imaging recording method and an apparatus for its implementation, including applying a light to an image to produce imaged light, passing the imaged light through a filter unit to provide filtered light, and recording the filtered light on an optical detector to produce a recorded image. The filter unit includes a first filter and a second filter. The first filter is polarization selective and the second filter is wavelength selective.
