Driving System for vertical Measurements with Michelson type interferometers.

摘要

The present Invention relates to a Driving System with Michelson Interferometer type vertical Measurements for Measuring the Wavelength of laser Light and other physical quantities depenTeeth of the production of Interferometric fringes, which comprises: a Driving System and an electronic unit that serves for the acquisition and display of Data,So as to generate the signal that controls the speed of rotation of the Pulley of the Driving System.The driving system has the function of producing the controlled Movement of the corners of a Cube that are part of an Interferometric System.The Driving System is characterized by a non-magnetic metal Pulley mounted on a ShaftDriven by three Coil FED each phase of the three-phase line for producing Eddy Currents induced in the Metal Disc; this creates a torque that produThe rotation of the Pulley.In addition, the additional Driving System comprises a Coil which generates a Magnetic Field on the Pulley, giving rise to a Magnetic Brake to control the speed and StabilizationRotation of the Pulley.The Feeding of the spool Braking was done by means of a Power Source controlled by a Voltage proportional to the frequency with which they are producing the interference fringes.Since this Frequency is also proportional to the speed with which Move The Cube Corner, The Magnetic Brake gives rise to the speed regulation.Moreover,The Cube Corner Hanging Pulley through flexible wires; Additionally, in one of the threads is added a counter Weight so that it has a Gravitational Lorca.Moreover, The Optical System of the return Signal, such that the Cube Corner retornanado automatically and are in their original positionFrom where to start automatically Cycle through transferring the torque of driving Gravitational torque produced by the coils Powered by three-phase Electric Power.The Electronic Unit is also responsible for the acquisition and display of the data of the signal from the Photodiode, Amplified, shaped pulseThe number of pulses, and finally shows the total number of pulses in a Digital Display.
