Abstract: PURPOSE:To prevent an error in the case of detecting a rotary angle as a quantity of light, to enhance an accuracy, to increase a measuring range and to eliminate an error due to temperature characteristics by so applying a magnetic field to a pair of Faraday effect elements as to cancel rotary angles of the elements. CONSTITUTION:A light from a light emitting element 1 is linearly polarized by a polarizer 2, incident on a pair of Faraday effect elements 3, 4, light from the elements 3, 4 are converted to light quantity by an analyzer 5, and converted to electric signal by a photoreceiver 6.

A magnetic field is so supplied from an electromagnetic unit 7 to the element 3 as to set the angle to zero, and a current to be supplied to the unit 7 is detected by a detector 8. Accordingly, since the magnetic field is so applied to the pair of elements as to cancel the angles of the elements 3, 4, approximation of sin 2theta 2theta is not necessary, and a measuring range is increased. Further, an error at the time of detecting the quantity of light and an error due to temperature characteristics can be cancelled by the analyzer 5.
