Abstract:
The present invention relates to an optical displacement sensor comprising a first at least partially reflective surface and a second surface having a diffractive pattern, the surfaces being provided on elements having a variable distance between them, each surface pair defining a cavity between them. The sensor also comprising at least one light source transmitting light at least one a chosen wavelength range into said cavities and at least one light detector receiving light from the cavities, wherein said diffractive patterns are adapted to direct light toward at least one detector provided in a known position relative to said diffractive surfaces.

Claim (Index 1):
An optical displacement sensor comprising:\n a first at least partially reflective surface and a second surface having at least three diffractive patterns, the first and second surfaces being provided on elements, wherein at least one of said elements is moveable to change a distance between the elements, so that the elements have a variable distance between them, wherein the partially reflective surface defines respective pairs together with each diffractive pattern, each of said pairs defining a respective cavity between them, each cavity having a respective optical cavity length; at least one light source transmitting light in at least one chosen wavelength range into said cavities; and at least one light detector receiving light from the cavities, wherein each pair is adapted to provide a maximum diffractive efficiency at chosen wavelengths within said range, said diffractive patterns being adapted to direct light toward at least one detector provided in a known position relative to said diffractive surfaces, the detector being adapted to measure the diffraction efficiency phase corresponding to each pair, thereby producing three or more signals which collectively allow measurement of a displacement between the first and second surfaces that is independent of an intensity of the light source; wherein the respective optical cavity lengths between the pairs provide respective phase offsets.
