Title: Speed detecting circuit
Inventor: KOIZUMI YUTAKA
IPC: G01P3/48
Filed: 1990-02-16
Abstract: PURPOSE:To decrease the drift in offset and to achieve the high speed in response by utilizing the output of a digital F/V converter for the DC component of a frequency modulated signal, and utilizing the output of an analog F/V converter for the AC component. CONSTITUTION:The transfer characteristics of a digital F/V converter 3, an analog F/V converter 4, an LPF 5 and an HPF 6 show a delay in first order. The respective transfer functions are as follows: G1 = 1/ {1 + (jw/w1)}, G2 = 1/ {1 + (jw/w2)}, G3 = 1/ [1 + (jw/w3)} and G4 = (jw/w0)/{1 + (jw/w0)}0. In these functions, (w) is a frequency, (j) is an imaginary-number unit, 1/w1, 1/w2 and 1/w0 are time constants and w0 < w1 < w2. Namely, the DC component of the output of the converter 4 is cut with the HPF 6. Therefore, the DC characteristic of the converter 3 itself whose drift of offset is less becomes the output of a speed detecting circuit. The transfer function G of the AC characteristic of the entire speed detecting circuit is expressed by G = 1/ {1 + (jw/w2)} = G2, the AC characteristic becomes equal to the quick response characteristic of the converter 4.

Abstract: PURPOSE:To evaluate an electrooptic effect by determining the change rate of a phase delay by voltage impression from the ratio between the output of a photodetector when the voltage is impressed to an electrooptic material and the output when the voltage is no impressed and from the phase delay of the electrooptic material when the voltage is not impressed. CONSTITUTION:A quartz substrate 2a is pressed to the electrooptic material M in the central part of a quartz substrate 2b and a function generator 3 is operated between electrodes 1a and 1b on the substrate 2a to impress the voltage to the material M. He-Ne laser light is polarized in a phi direction by a polarizer 4 to linearly polarized light which is entered to the material M. The theta component of the transmitted light thereof is taken out by an analyzer 5 and is detected by the photodetector 6. The ratio R between the change rate of the output of the detector 6 by the impression of the voltage to the material M and the output of the detector 6 when the voltage is not impressed is determined. The phase delay delta by the double refraction of the material M when the voltage is not impressed is simultaneously determined and the change rate DELTAd of the phase delay by the voltage impression is calculated from the output ratio R and the phase delay delta. The evaluation of the electrooptic effect is permitted by determining the electrooptic characteristic from the change rate DELTAd.
