    摘要: The present invention relates to an arrangement for measuring relative movement. The measuring arrangement comprises a light source (110, 210) for emitting a light beam, a moving element (120, 220) having a reflective surface (121, 221) adapted to reflect a first wavefront portion of the light beam, and a reference element (130, 230) having a reflective surface (131, 231) adapted to reflect a second wavefront portion of the light beam. The arrangement further comprises detecting means (140, 240) for detecting changes in a spatial interference pattern produced by the light reflected from the moving element and the reference element, and processing means (150, 160, 250, 260) for calculating the relative movement between the moving element and the reference element from the phase change in the detected spatial interference pattern. The invention also relates to a method for measuring relative movement.

    摘要: A procedure for enhancing the resolution of spectral data, in which the Fourier self-deconvolution method FSD is used to produce from the input spectrum a data set in an interval 0-L.sub.t, the maximum entropy method MEM is used to compute prediction error filter coefficients {a.sub.k } from this data, and by the linear prediction method LP, using coefficients {a.sub.k } and data points 0 to M. Data are predicted in the interferogram I(x) beyond L.sub.t, whereby output spectrum maximum line narrowing with minimum distortion is achieved.

    摘要: A detector arrangement for electromagnetic radiation has at least an absorbing element and a cantilever sensor which are in operational connection with each other, so that the sensor is bendable in response to electromagnetic radiation absorbed by the absorbing element. The arrangement further includes an interferometer for measuring bending of the cantilever sensor. In a method for measuring electromagnetic radiation, electromagnetic radiation is directed on to the absorbing element and thereby bending of the cantilever sensor is caused. Bending of the cantilever sensor is measured with an interferometer. The cantilever sensor can be a door-like flap made of silicon, attached to one side of a frame of silicon.
