Abstract

A holographic interferometric method applied to the measurement of physical fields through the use of fibers is presented. In this method, a hologram, carrying the information of optical elements in the object beam, is made and set behind the output end of the optical fiber. This reconstructed object wave of the hologram is used as the measuring reference wave. When part of the fiber in the object beam is put into the measured physical field, the change of some parameter in the physical field should appear in the optical wave launching from the optical fiber, called the informational object wave. The interference field is formed behind the hologram by the informational object wave, and the measuring reference wave and parametric change of the physical field are revealed by the change in the interference field intensity.
