Now I want to say few about latest technology in three dimensional image presentation, which is in trails still!those are halowgraphy,claytronics,sorry i am not particular about spellings.
first is halowgraphy which is a three dimensional representation of any thing.in this the image of the things whatever it may be, will be recorded on a photographicplate in the presence of some typhical light's wavelength.when the same wavelength light is passed again through that photo graphic plate the three dimensional image of recorded image is appears.but there will be no moment at all,it would be still in the position in which it is recorded.but the second technology is very advanced.before telling about this i want to bring some reminesense of urs.I think every one of u have seen the movies starwars,if not atleat the movie jeans(telugu).in starwars in some situations some kind of devices like phone(just 4 an idea) is used in which the three dimensional image of the person who is speaking from else where can be seen in air,the moments of image is also act as the original person who is talking from else where.and jeans the famous song "kannulatho choosaydhi guruvaaa!" twin iswarya appears,where one was image created by computer prjector,ressembles the actions of rajusundaram(madaesh) wearing some wires aroud his body.ofcourse that's the mixture of claytronics and some advanced.but this is the main thesis of claytronics.this is still in embrayo stage in implementation,ofcourse can be say impossible to see soon.in here the three dimensional image of the person or thing will be recorded, in the other side some chambers will be there to project the image as it is.to project the image in air we have to take control over the photons of air.here the problem comes,in projecting side we have to control the every photon in air to project the actions of person completely.there would be lakhs of protons,burden to control each and every one either by a software or any other technology.so it is said to be impossible.
that's it the story behind the technology behind jeans and starwars.I hope u like it!
