A Semiautomated Device for Measuring the Geometric Parameters of Charged-Particle Tracks in Photoemulsions
Lately, in order to increase the speed and accuracy of measurements of the parameters of charged particle tracks in nuclear photographic emulsions, considerable importance has been attached to semiautomated scanning and measuring devices. A great many such devices have been designed and built [1–10]. Usually they comprise a standard or specially fabricated instrument microscope and specialized ancillary equipment. Other special equipment is used to convert the instantaneous coordinates of the microscope platform into digital numbers. Sometimes the platforms are equipped with drive motors. Electronic devices utilizing perforation or magnetic recording techniques transform the acquired information into a form suitable for input to digital computers. In some case the required computations are performed in the instrument itself, and the readout of data is accomplished by means of digital printers [4, 6, 8]. The participation of the operator in semiautomated devices is limited to visual inspection of the photoemulsion and tracking of the particles by manual or motor-driven control.
