摘要: The invention relates to a Fabry-Perot interferometer and a method for producing the same. More specifically, the invention relates to Fabry-Perot interferometers which are controllable with one or several actuators, such as piezoelectric, electrostrictive or flexoelectric actuators. In prior art technology there is a problem to achieve a sufficiently small and uniform gap between mirrors. In the present invention an intermediate structure (85a, 85b, 95a, 95b, 81a, 81b, 91a, 91b, 98a, 98b) is used between a mirror and an actuator or between two mirrors. The method of production also includes measuring the width distribution of the gap in several phases, and providing pre-actuation of actuators.

摘要: The invention relates to a system and a method for optical measurement of a target, wherein the target is illuminated, either actively illuminated, reflecting ambient light, or self illuminating, and a measurement light beam received from the target or through it is detected. The prior art optical measurement systems generally include mechanical filter wheels and photomultiplier tubes, which cause the equipment to be expensive, large-sized and often not sufficiently accurate and stable. The objective of the invention is achieved with a solution, in which the illuminating light beam and/or measurement light beam is led through a Fabry-Perot interferometer or a set of two or more Fabry-Perot Interferometers, and the Fabry-Perot interferometer or a set of two or more Fabry-Perot Interferometers is controlled into different modes during the measurement of a single target. The invention can be applied in optical measurements where, for example, reflectance, absorption of fluorescence of the target is measured.

摘要: The invention relates to a method for attenuating magnetic interference in a test room (1, 2, 8, 9) equipped with a shield of ferromagnetic material, in which method the interfering magnetic field is measured and a compensating field is generated on the basis of the measurement result. According to the invention, the interfering field to be measured is resolved in three magnetic field components oriented in different directions, each one of said magnetic field components (x, y, z) is measured with the help of coils (3, 4, 5, 6) wound about the wall elements (1, 2, 8, 9) made from said ferromagnetic material in a manner wherein a flux component passing through at least one of the wall element (1, 2, 8, 9) made from said ferromagnetic material that is oriented parallel to one of said magnetic field components (x, y, z) is measured with the help of coils wound about said wall element.
