Title: Fizeau fourier spectrometer
Inventor: TSUJITA KAZUHIRO
IPC: G01J3/45
Filed: 1993-04-16
Abstract: PURPOSE:To allow stabilized generation of interference regardless of disturbance by disposing a reflection means such that the incident light to a double refraction medium is split into two light beams which are reflected and combined after leaving the medium. CONSTITUTION:Light a1 from the surface of a specimen 10 is condensed 21 and directed toward a double refraction medium 23 where it is split into a normal light beam a3 and an abnormal light beam a4. The light a3 is reflected on a half mirror 23 and leaves the medium 23 while aligning the axis with that of the incident light a2. The light a4 transmits through the mirror 23a and reflected on a mirror 24 to impinge again on the medium 23 and leaves the medium 23 while aligning the axis with that of the light a2. The lights a3, a4 then advance on the same optical path as the light a2 in reverse direction and impinge on a polarizing plate 25. Predetermined plane of polarization components interfere with each other and detected by an optical detector 27 which delivers a light intensity signal to a Fourier spectrometric means 31. Since the optical paths of the lights a3, a4 are substantially aligned, the both lights are effected equally by the disturbance thus enhancing the accuracy in the measurement.

Abstract: PURPOSE:To obtain a sensor capable of easily measuring the absolute distance from an object to be measured and requiring no correction operation, by compounding one group of light emitting fibers and two groups of light receiving fibers to form one optical fiber sensor. CONSTITUTION:The end surface of an optical fiber bundle 10 is constituted of light emitting fibers 14 and light receiving fibers 16a mixed at random and the light receiving fiber bundle 12 of the peripheral edge part of said optical fiber bundle 10 is constituted only of light receiving fibers 16b. When one optical fiber sensor is constituted by this method, the lights emitted from the fibers 14 are reflected from the surface of an object 18 to be measured and separately detected by the optical sensors of the fibers 16a, 16b. A distances VS light quantity characteristic expressed by a curve A is obtained from the fibers 16a and a curve B is obtained from the fibers 16b. Since these curves have a property changing in a vertical axis direction but not shifting in a transverse axis when the reflectivity of the object 18 to be measures changes, the ratio of measured light quantities is collated with the ratio of the outputs of the curves A, B to make it possible to calculate a distance.
