Show PICTURES SENT BY RADIO, IS 0LAI1 EXPLANATION GUN WRITER Man Who Made Movies' Possible Originates Radio Method PICTURES SECRET Great Possibilities of Send-: ing Photos By Means of Wireless BY l.l ni M TIIll.KUi I (Copyright, by XEA Service) WASHINGTON, May C Francis i Jenkins, noted Inventor, has given i .EA Service the first public explana-l lion of an epoch-making invention : the long distance camera. Radio photography, says Jenkins. Is an accmpllshed fact. j Photographs perhaps even motion pictures can be sent by wireless: The new Invention includes a device by which pictures can be sent secret-ly secret-ly a tremendous weapon in warfare and criminology. The first hint of this startling invention inven-tion was given by Jenkins at a closed meeting of the Society of Motion Picture Pic-ture Engineers, of which he Is the founder. In Boston. B, spei lal per-i per-i mission Of the society Jenkins gave an Interview to the writer dcsc'riblns the ,detealls of his discovery. II VKES M li s POSSUM E Jenkins is the man who Is given 'credit for making movies possible by Inventing the Intermittent movement ;of the projector. "Within a year." said Jenkins, "I expect to have apparatus so perfected perfect-ed that long distance cameras' with .sending set and receiving set will be jln the hands of the public for sending send-ing photographs by radio any dis-I dis-I lance 1 I have sent pictures from one room to another In my laboratory. The pictures pic-tures are faithful m every detail. 1 "Two prismatic glass discs are used in front of the lens to take the picture. pic-ture. The view is caught by a sensitive, sensi-tive, photo-electric cell, which Is connected con-nected to an ordinary radio sending set. I Bl wis STEPPED IP "Beams of light are stepped up to high frequency electric waves and arc sent In the same manner as sound waves are translated Into wireless wire-less waves and broadcasted "At the receiving end a new device is attached in dace of the ear pieces r.OW In use and the wireless waves are stepped down into beams of light 'and the image taken far away is im-1 im-1 pressed on the negative, As in an ordinary camera, the negative is Ho n developed and oph .s printed I "By another system lh' image. In? - e "I Of reaching a negative at the re-delving re-delving end can be thrown directly on a screen " The prismatic rings, Jenkins said, were the invention of another. one pair revolves in front of the lens und a second pair at the receiving end LIKE R 1DIO Nil PHONY "Radio photography is the same as radio telephony ' he said. "Wireless waves are Impressed with picture characterizations Instead of sound ; characterizations. The picture sending set takes the pface of the laudlon and the receiving set takes the place of the telephone receivers." I Naval authorities already have pointed out to Jenkins the tremendous tremen-dous possibilities o sending secret ' pictures. 'The picture send .in radio has im-1 im-1 printed in one corner 8 tin black 'spot." Jenkins explained. "This IS the synchronising spot. without it the man at tho receiving end cannot get the picture. I 'The spot tells him where to focus. ! p.eforo the picture Is sent, word la sent by radio telling him whether the kv n-clironlzlng n-clironlzlng spot Is in the upper left hand corner, upper right, lower renter ' or wherever the sender wishes. kORBE N SPOl "Or a definite place for the synchronizing syn-chronizing spot can be agreed upon In advance. "Bv this means plcture.s of enemy positions and a thousand and one other things caught by cameras can be transmitted secretly by wireless "A photograph need not be taken first and then -sent bv radio A camera cam-era With 'in inexpensive portable jaerlul can take the picture and at the same time automatically send II Secretl tO v certain receiving set or broadcast It generally "Pictures of criminal suspects can be taken and Instantly duplicated In every police station In the countrv "Devices for both sending and receiving re-ceiving probably will not cost over fr.O making possible wide commer-'clal commer-'clal use." |
