The invention relates to the technical installation for visualization of electrostatic images, in particular to the metrologic engineering provided for measurement of dynamic deviations of the exterior dimensions of the photothermoplastic data-carrying medium when during recording the optical information on a real time basis. The vertical optimeter includes a support, onto which it is installed an optical system, containing a tube with light source, a visualization tube provided with a video camera, a mechanism for rough control of the cell motion for optical recording on the photothermoplastic medium.The vertical optimeter additionally contains two more optical systems: one installed coaxial with the first optical system, includes a visualization tube provided with a digital video camera, a semitransparent mirror installed onto the support over the axis of the visualization tube.The other optical system, sensitive to the infra-red radiation, is installed onto the support and contains. The consecutively joined a detector of the infra-red radiation, an amplifier, an electric drive, joined with the cell for optical recording of the information.The result of the invention consists in excluding the optical errors, due to the fine control of the optical data recording cell motion and due to the recording of dynamic errors, released from both sides.Claims: 1Fig.: 1
