Photographs Radioactivity in 3-D
Chemical & Engineering News · 1955
A STEREOSCOPIC viewing system, designed and built by E. Leitz, permits atomic scientists to see and photograph radioactive specimens in 3-D. The device is a periscopic, stereoscopic telescope which permits scientists on the outside to look at "hot" materials within t h e cell, behind concrete walls three feet thick. This new aid enables scientists to keep a record in three-dimensional pictures of radioactive materials' surface contours, says Richard W. Luce, chief engineer of Leitz and developer of the viewing system. Stereoscopic pictures are taken by a special Leica camera that is attached to the telescopic system. The camera's lens is removed because the lenses of the telescopic system transmit the image. Luce adapted a new kind of Leica, called the 72, to the telescope. This camera gives 72 exposures half the size of ordinary 35-mm. pictures and is said to be useful in general visual examination work. Mounted for stereoscopic work in the atomic ...
