Abstract: The invention relates to temperature compensated micro-electro-mechanical (MEMS) resonators (300) preferably made of silicon. Prior art MEMS resonators have a significant temperature coefficient of resonance frequency, whereby it is difficult to achieve a sufficiently good frequency stability. The inventive MEMS resonator has a resonance plate (310) which resonates in Lamé mode. The resonance plate is p+ doped material, such as silicon doped with boron, and the concentration of the p+ doping is such that the plate has a temperature coefficient of resonance frequency near to zero. The tensile stress and the second order temperature coefficient can further be reduced by doping the plate with germanium.

Abstract: An optical radiation processing unit directs different wavelengths of the optical radiation emitted by an optical source to an object being measured from a direction that differs from the normal of a surface being measured so that the different wavelengths focus on different heights in the direction of the normal of the surface. A possible polarizer polarizes the reflected radiation in a direction perpendicular to the normal of the surface. The optical radiation processing unit directs to a detector polarized optical radiation that received from the object. The signal processing unit determines on the basis of a signal provided by the detector from the detected radiation the wavelength on which radiation is the highest, and determines the location of the surface by the determined wavelength. When measuring an object from both sides, the thickness of the object being measured is determinable using the locations of the surfaces.
