20120038928 | SYSTEM AND METHOD FOR OPTICAL MEASUREMENT OF A TARGET - 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. | 02-16-2012 |

20150124263 | Fabry-Perot interferometer and a method for producing the same - 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 ( | 05-07-2015 |

20140176729 | METHOD FOR DETERMINING CALIBRATION PARAMETERS FOR A SPECTROMETER - An imaging spectrometer includes a Fabry-Perot interferometer and an image sensor having color-sensitive pixels. The interferometer has a first transmission peak and a second transmission peak (PEAK2). A method calibrating the spectrometer includes providing first calibration light, which has a narrow spectral peak, obtaining first detector signal values from the image sensor by coupling the first calibration light into the spectrometer when the reference spectral peak is near a first spectral position, obtaining second detector signal values from the image sensor by coupling the first calibration light into the spectrometer when the reference spectral peak is near a second spectral position, providing second calibration light, which has a broad bandwidth, and obtaining third detector signal values from the image sensor by coupling the second calibration light into the spectrometer. | 06-26-2014 |

20120200720 | METHOD OF COMPENSATING FOR TURBULANCE WHEN RECORDING FILM SEQUENCES - A method of compensating for atmospheric turbulence when recording film sequences. A frame for an image that is being currently recorded is compared at pixel level with a number of frames recorded earlier. Each pixel value in a current frame is compared with pixel values in earlier frames. A matrix is adjusted upward by one unit at positions where a new value is encountered at the positions. Values adjusted upwards in the matrix are retained for a limited number of frame comparisons. A summing window is drawn over the matrix and movement is deemed to have occurred in areas where a sum from the summing window exceeds a limit value. A compensated frame is created. All pixel values in areas where the summing window exceeds the limit value are derived from the current frame. Other values are derived through a temporal median filtering of a number of earlier frames recorded. | 08-09-2012 |
