Title: Optical filter
Inventor: MURAKAMI TAIJI
IPC: G02B6/34
Filed: 1977-12-05
Abstract: PURPOSE:To eliminate the need for optical axis adjustment and provide a small filter of sharp rise by making use of the optical loss of a single mode waveguide of different radii of curvature or multiple waveguides of the same radius of curvature. CONSTITUTION:The incident light to a single mode optical guide 1 with an external layer is bisected to the guide light by the core part 4 and the radiation light reflecting at the boundary 6 with the external layer of the clad 5 of a refractive index n2 smaller than that of the core part 4 and a half-amplitude level (b) by the bent parts whose radii of curvature R1 thru R3 become subsequently smaller. When the conditions of the formulas I, II wherein the phase difference of the radiation light and guide mode becomes N(integer) times of 2pi are satisfied, coupling of the radiation light and guide light becomes maximum and the guide light is converted to the radiation light, which is then radiated to the outside from the reflection point of the boundary 6, thus the light loss of the guide light becomes large. (In the formulas beta : the phase constant of the guide mode, K : the number of light waves of free space)

Filed: 1983-08-09
Abstract: PURPOSE:To prevent the wrong result of measurement from being utilized and to enable selection of the most adequate result of measurement by emitting the 2nd signal indicating that the plural results of measurement exist by discriminating the same from the 1st signal indicating that the measurement is substantially infeasible. CONSTITUTION:A difference between the max. value and min. value of a video signal is taken with one or both of both signal trains and detection is made that the distance measurement is infeasible on account of excessively small contrast of the light intensity possessed by an object. Said detection is accomplished in the form of converting the video signal to the pulses having the pulse width indicating the light intensity. The 1st means emits the 1st signal by detecting that the measurement is substantially infeasible. The 2nd means which detects the existence of plural amts. of shifts to attain the max. coincidence of the two video signal trains and emits the 2nd signal indicating such existence is provided. Such detection is accomplished by feeding the read-out pulse to the shift register thereof and counting the number of the logical values outputted successively from the end of the shift register.
