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 and device for reading an electronic code. An alternating electrical signal is brought to the code being measured with the aid of electrodes, and the current or voltage travelling through the electrodes is measured. The real and the imaginary components of the current or correspondingly the voltage are defined. The electrodes, being on an essentially lossless surface, an angle correction is made to the real and imaginary components of the current or the voltage in such a way that substantial changes in the current take place only in the imaginary component of the current or voltage.
