PURPOSE:To easily form a negative image for an overhead projector (OHP) not causing deterioration of visual recognizability due to an underlaid negative layer by forming a surface-roughened diffusion reflecting layer on a paper for the OHP with a light transmitting toner, and forming a toner ...
Overhead projector LCD panel for image processing The use of a commercially available LCD panel of an overhead projector is suggested for coherent optical processing as a low cost SLM in this paper. The LC... SC Jain,SD Mehta,M Singh - Systems-oriented Optical Design: Conference on Systems...
An overhead projector having scanning device for scanning an original image thereby generating electric signals corresponding to the original image, selecting device for selecting one of a thermochromic film and a thermographic paper, a ... T Nakamura,Y Saka - US 被引量: 27发表: 1989年 Display...
A dramatic demonstration of the SFM effect requires only an overhead projector and a paper clip. If one bends the paper clip into a complicated shape, and lays it on the surface of the overhead projector, the image projected is a two-dimensional (2-D) reflection of the twisted wire. Thi...
overhead projector: as an image goes out of focus, it gets blurry! Specifically, the edges become blurred so that it is harder to distinguish the exact point where the image transitions from bright to dark. In other words, the slope of the aerial image at the edge between bright and dark...

;CONSTITUTION: A lower plate 8 is provided to be freely rotatable with centering the optical axis 4b of a condenser lens 4 as center on the housing of the projector main body of an overhead projector. The lower plate 8 is constituted so that at least, a part corresponding to the ...
A projector with two levels of illumination for projecting images from a film transparency is disclosed. Monitoring circuitry configures the level projector for the appropriate lead of illumination depending upon an operator request for preview illumination or a heightened level of illumination for exposure...
Liquid-crystal displays have been developed for projecting computer or video images on an overhead projector. An example of such a display is the Ovation 820C 8.4" diagonal color active-matrix liquid-crystal projection panel from Proxima Corp. of San Diego, Calif. or models QA-1260 and QA-16...
