Abstract
PURPOSE:To perform the compensation of temp. by utilizing transmitted light having a wavelength receiving light absorption, by using a Faraday element having a characteristic absorbing light having a predetermined wavelength within a predetermined temp. range, a light source having a wavelength receiving light absorption and a light source having a wavelength receiving no light absorption. CONSTITUTION:The light of the first light emitting element 12 of a wavelength containing a light absorption terminal wavelength and that of the second light emitting element 13 of a wavelength containing no light absorption terminal wavelength are incident to a Faraday element 4 having a light absorption terminal characteristic at predetermined temp. Transmitted lights are respectively incident to optical filters 14, 15 permitting the passage of the wavelengths of the first and second light emitting elements 12, 13 to detect an electric signal having received the effect of temp. and an electric signal having received the effect of a magnetic field. The signal having received the effect of temp. is inputted to a temp. converting circuit 20 through a DC filter 18 and the output thereof is inputted to a temp. compensation circuit 21 as the temp. compensating signal of the signal based on the magnetic field from a divider 10.
