ABSTRACT:
An optical sensor including a plurality of optical elements such as lenses, a polarizer, and analyzer, optical fibers, and a Pockels element or Faraday element. Light from a light source is transmitted through the optical elements of the optical sensor to optically measure applied voltage or an electric field acting upon the Pockels Faraday element on the basis modulation of the light received by a light receiver. The optical sensor includes a first synthetic resin interposed between adjacent optical elements in close contact with the optical elements without gaps, and a second synthetic resin of the same material as the first synthetic resin filled around the optical elements. The optical elements may be bonded to a base plate for adjusting optical axes of the optical elements, and the second synthetic resin may be filled around the optical elements and the base plate.
