摘要： The invention relates to a bolometer element, a bolometer cell, a bolometer camera, and a method for reading a bolometer cell. The bolometer cell comprises several bolometer elements. Each bolometer element comprises a first bolometer having a first heating resistance for sensing radiation power acting on the element, and a second bolometer having a second heating resistance, and in each bolometer element the first and second bolometers are electrically connected to each other in such a way that the heating resistance (611) of the first bolometer can be biased with the aid of a voltage through the heating resistance of the second bolometer in order to amplify the radiation power detected with the aid of the connection. With the aid of the invention, it is possible to implement an extremely sensitive bolometer camera.

摘要： A method for capturing images of a person for a security screening is provided. A spatial position of the person is detected using a support sensor. Information indicative of the detected spatial position of the person is then received and used to steer a field of view of at least a first set of imaging heads towards the detected spatial position of the person. The at least a first set of imaging heads includes at least one passive imaging head and at least one active imaging head, wherein the passive imaging head captures separate images corresponding to at least two frequency bands at a same time. Images of the person are then captured with the at least a first set of imaging heads.

摘要： The invention relates to detection performed over millimeter and submillimeter wavelengths, especially to imaging solutions functioning over a submillimeter-wavelength range. The system of the invention uses detectors, comprising antenna coupled bolometers together with wavelength selective optics. The detector matrix is preferably curved for reducing the number of imaging errors. In order to provide a curved detector matrix, the detector matrix is constituted by flat submatrices, each being provided with one or more integrated antenna coupled bolometers. The detectable frequency range is preferably limited in two stages, first by means of wavelength selective optics and secondly by means of the operating band of the antenna of an antenna coupled bolometer. In order to focus the incoming radiation on bolometers, the bolometer substrate is fitted or the surface or interior of the bolometer substrate is provided with a bolometer lens or a corresponding optical element in alignment with each bolometer.

摘要： An antenna-coupled microbolometer structure comprises a substrate (301), an antenna (102, 103) supported by the substrate, and a thermally sensitive element (101, 305) connected to the antenna and arranged to dissipate electric currents induced into the antenna. Both the antenna (102, 103) and the thermally sensitive element (101, 305) comprise material that is susceptible to achieving a superconductive state below a certain critical temperature. The thermally sensitive element (101, 305) is supported at a distance from the substrate (301) leaving an empty gap (306) between the thermally sensitive element (101, 305) and a surface of the substrate (301).
