A number of proposals have been put forward for the extraction of three dimensional data from a pair of electron microscope photographs taken from different angles. The methods used have, in general, been either point by point analyses or rather inconvenient. This paper shows that an existing photogrammetric plotter of topographic accuracy can, with very simple modification, be converted to give continuous plotting facilities from certain such micrographs.
