    摘要: This invention relates to an interference filter, especially for use in gas detection with infrared light within a chosen range, comprising at least two essentially parallel and partially reflective surfaces with a chosen distance between them thus defining a cavity delimited by the reflecting surfaces between which the light may oscillate, and wherein at least one of said surfaces is partially transparent for transmission of light to or from said cavity. The filter comprises a first transparent material having a high refractive index, e.g. silicon, positioned in at least a part of said cavity, and at least one of said reflective surfaces being divided into a three dimensional pattern with varying shift relative to its plane, thus to provide a position dependent resonance condition between them for separation of different wavelengths in the light.

    摘要: The invention relates to a micromechanical unit, in particular, an adjustable optical filter, and also a method to manufacture the unit. The unit comprises a first device layer and a second substrate layer at least partially fastened to each other, where the device layer comprises a number of reflecting elements divided between a number of non movable, fixed reflecting elements, where the fixed elements are connected with the substrate, and where a cavity is defined between the substrate and each movable element and each movable element is set up to produce a spring-loaded movement into the cavity, and where a number of dielectric spacer blocks are placed in the cavities between each movable element and the substrate to avoid electric contact between them.

    摘要: To achieve gas detection in a precise and reliable way, but at the same time without consuming too much energy, a gas detection system is provided which generally comprises a pair of two different gas detectors. The first detector (DLP) is active continuously and sense substantially for an unspecific change in the local gas mixture. As a reaction upon the change, the second detector (DHP) of the pair is activated. This detector (DHP) performs the determination of the concentration of a specific gas or several specific gasses. The second detector (DHP) may be of a type which consumes more power, but will be active for a short period of time before returning to an inactive state where only the first detector (DLP) is active. The first detector (DLP) however is of a type using little power.
