Electrostatically scanned reflectors for interferometer and laser applications.
The paper describes the design and performance of an electrostatically scanned film reflector. A drive scan sensitivity of better than a wavelength per volt at 6328 A can be achieved with the use of appropriate polarization voltages. The power requirements for both polarization and drive may be made extremely low. In addition the device is capable of good optical properties together with large linear displacements. It should find wide application in interferometer and laser systems, particularly in the infrared region of the spectrum.
