Patent GB-2185123-A (GB)
Title: Digital optical phase-shifter
Inventor: EVEREST FRANK G
IPC: G02F1/035
Filed: 1986-12-23
Abstract: An integrated optical phase-shifter, say of z-cu lithium niobate 10 with a titanium-diffused optical waveguide 11, has an array of field-applying electrodes 13,13' extending along the waveguide. The electrodes have different lengths in accordance with a binary sequence and are driven by respective bits of a multiple-bit digital signal to cause a phase-shifting electric field to appear through a controllable overall proportion of the length of the waveguide. Thus, instead of controlling the degree of phase-shift by varying the strength of a fixed length field, the effective length of the field is controlled. This enables the phase-shifter to be directly digitally controlled, ie without any need for a digital to analog converter. The phase shifter has application to a fibre-optic gyroscope. <IMAGE>

Title: "rms waveform sensing"
Inventor: DAVY PETER GORDON
IPC: G01R19/02
Filed: 1991-11-22
Abstract: A method of sensing the rms value of a phase chopped sinusoidal electrical waveform comprising the steps of combining an input signal (8) representative of the waveform with an auxiliary signal (17) in a combining circuit (14, 16) which produces a combining circuit output (19) equal to whichever is the greater of the auxiliary signal and the modulus of the input signal, and averaging the combining circuit output over at least one half cycle of the wavweform.
