Camera Filter Cuts Through Fog, Camouflage
Many people know how helpful polarized sunglasses are in cutting the glare coming off water on a sunny day But a filter that could let people see or block out all the polarizations of visible light would do much more than just make a day at the beach more comfortable Such a filter could also help pilots see through fog haze or clouds of dust military members spot cars and trucks even when theyre camouflaged and doctors see through certain layers of human skin.If your current sod is larger when compared to a half-acre, an important going lawn mower would definitely be your favorite ideal variety
In a Air Force funded project a group of physicists from the Colorado School of Mines have created a filter that detects circular polarized light which is more difficult to isolate than the linear polarized light that sunglasses filter They reported their research in the journal Optics Express.The to-do checklist on this sort of organizers support the businessmen by slicing along the time and work invested on carrying out day time to wholesale car electronics
The human eye detect the different polarizations of light so it can be difficult to imagine what a circular polarized filter can do Images from linear polarized light cameras which scientists have already made can help In this brochure by University of Arizona optics researcher Russell Chipman Figures show how linear polarized light filters cut through haze and camouflage The images that our filter would allow to be made would be similar but would contain even more information said David Flammer one of the physicists who developed the new circular filter.If your budget is tight consider a smaller gift of high quality. Recipients will thank you for thank you gifts
Flammer and his colleagues havent yet made a camera that can take a picture using their filter however so they arent sure exactly what might show up with some circularly polarized light filtered It may be a year or more before they can make a camera said Russell Hollingsworth senior scientist at ITN Energy Systems a company that is working with the School of Mines to commercialize the filter
