Title: Received signal processing method for optical fiber backward scattered light
Inventor: OGAWA KATSUNORI
IPC: G01D5/353
Filed: 1988-03-14
Abstract: PURPOSE:To reduce measurement errors of backward scattered light intensity and a reflective index at respective points in an optical fiber by an OTDR method by solving a prescribed expression. CONSTITUTION:The equation I is solved to obtain the backward scattered light intensity or reflective index from respective points in the optical fiber. In the equation I, a number is 0, V is the distance of a measurement end, the light velocity in the optical fiber DELTAX=DELTAt.V/2, and R0, R1...Rn are coefficients. In an expression II, Po0, Po1...P0M are coefficient. In an expression III, P0, P1...PM+N are coefficients. In an expression IV, T2n is a coefficient. In an expression V, Tn=T1n<2>.T2n. In this case, the equation I is based upon the fact that data at each time which is measured by the OTDR method is the sum of the intensity of backward scattered light from several points corresponding to a spread of incident light pulse width, so an averaging process circuit averages signals, for example, 2<16> times by using the synchronizing signal from a pulse light source to obtain the intensity, reflective index, etc., of the backward scattered light from obtained waveforms by using prescribed expressions in order. Thus, the distribution state of external factors such as loss to the optical fiber, etc., is detected accurately, easily, and economically.

Abstract: PURPOSE: To well maintain a embedded matter embedded underground by spraying tervalent iron compds. around the circumference of the embedded matter, thereby prohibiting or substantially prohibiting the activation of microorganisms, such as sulfuric acid reducing bacteria and methane forming bacteria. CONSTITUTION: The corrosive microorganisms, such as sulfuric acid reducing bacteria, live in some cases on the circumference of the underground embedded matter, i.e., under the ground and the gas generating microorganisms, such as methane forming bacteria, are included in some cases in the embedded matter (including waste). These microorganisms, such as sulfuric acid reducing bacteria and methane forming bacteria are the microorganisms which use org. matter under the ground or in the embedded matter 1 as nutrient sources. The corrosive microorganisms and the gas generating microorganisms are relatively suppressed in some cases if iron reducing bacteria 3 which more preferentially consume the org. matter are preferentially propagated.  The iron reducing bacteria 3 can become more dominant than the microorganisms, such as sulfuric acid reducing bacteria and methane forming bacteria, if the tervalent iron compds. which are the nutrient sources exist in a large amt. The tervalent iron compds. 2 are sprayed around the embedded matter to propagate the iron reducing bacteria 3.
