Abstract

At present the taking rate of raster high-speed photography is limited mainly by two factors: (1) the grain size of the photo-sensi-tive emulsion; (2) the size of the image formed by individual raster element. To reduce the grain size of the film while maintaining its speed is the honorable duty of the photo-chemists. To reduce the image size the engineers have endevoured to machine the dies with which the lenslets forming the lenticular plate is pressed as fine as possible, and is reported that the diameter of each lenslet has been reduced to 60/urnin U.S.S.R.1)2) It seems dif-ficult to get further reduction. With the birth of grin fibre or sel-foc fibre a new way is opened to make the image size still slaaller and indeed the more efficient way is to use the tapered grin fibre, forming images of the secondary and tertiary order of increasingly smaller sizes.
