Abstract

An improved control unit for the high-speed photorecording camera VFU-1 is explained. Compared with the original control desk it provides a wider range of the recording camera mirror rotation frequencies of 600 - 80,000 revs/min with better stability of +/- 10% at the minimal rotation frequency. The basic unit provides 3000 - 75,000 revs/min with stability +/- 20% at the minimal rotation frequency. Other features include smooth control of the rotation frequency and two subranges of rotation frequencies. The improvement in stability is achieved by using a dc voltage stabilizer of the camera electro-motor feed at low rotation frequencies. The features of the motor are taken into account. The shortcomings of the basic control unit are corrected, which makes it more convenient in operation. The application of the unit extends the range of scanning velocities up to 4.8 - 640 m/s, and so extends the potentialities inherent in VFU-1.
