Abstract: A heterodyne interferometer has four fibre optic light guide sections (1, 2, 3, 4) applied to a lithium niobate crystal (CR) by titanium diffusion and interconnected by a polarization divider (T1). One of the light guide sections passes through an electro-acousto-optico converter (M1) in which monomode light (S) is supplied. Each light fraction of a polarization (TM, TE) is sent to a reference branch and a measurement branch from where the light, reflected and/or modulated by a 1/4 wavelength plate, is returned to the waveguide sections (2, 3). It then passes through the polarization divider (T1) and the fourth waveguide section (4) to a second polarization divider (PBS) and from there to photodetectors (D1, D2), where it is evaluated. Other embodiments are disclosed. The interferometer has a high light yield and a broad measurement range and is suitable for use in anemometers, devices for measuring speed and vibration, and displacement sensors.

Abstract: In optical branching equipment (44₁) which is supplied with an optical signal of a first wavelength band from a trunk line terminal equipment via a trunk line cable (30₀) and is inserted in the trunk line (30₁), the optical signal is normally provided to the trunk line cable (30₁) after being bypassed from a branching circuit (OP₁) to branch line terminal equipment (40₁) connected to a branch line cable (61₁), and when trouble develops in the branch line, the optical signal is delivered to the trunk line cable (30₁) via a short circuit (OP₃). In the short circuit (OP₃) there is inserted an optical limiter amplifier (29) which is capable of amplifying light of the first and second wavelength bands. Normally the optical limiter amplifier (29) is saturated by control light (C) of the second wavelength supplied from the branch line terminal equipment (40₁) via the branch line cable (61₁), and consequently, the optical signal of the first wavelength band is suppressed. When the supply of the control light (C) is stopped by some cause, the optical limiter amplifier (29) amplifies the optical signal of the wavelength band provided to the short circuit (OP₃) and provides the amplified optical signal to the trunk line cable (30₁).

An accumulator (39) accumulates the step value and, when the accumulated output exceeds 2mπ (where m is a positive integer), causes an overflow and a sign signal indicating the sign of the overflow. The digital ramp signal, which is the accumulated output, is converted by a D/A converter to an analog signal, which is provided to the optical phase modulator (17) A second error signal detector detects, as a second error signal, the difference between the outputs of the opto-electric converter at an operating point when the overflow occurs and at the immediately preceding operating point. Based on the overflow sign signal and a sign signal indicating the sign of the biasing signal at the time of occurrence of the overflow, a negative feedback control circuit determines which of +(4m-1)×π/2, -(4m-1)×π/2, -(4m + 1)×π/2and + (4m + 1)×π/2the operating at the time of occurrence of the overflow corresponds to, and multiplies the second error signal by a positive or negative sign dependent on the result of determination to create a negative feedback error signal, thereby controlling the conversion gain of the D/A converter.
