Title: Measuring radiation values and optical parameters - sampling half-space in spherical coordinates and determining spectral distribution of solid angle elements
Inventor: RIEMANN MANFRED PROF
IPC: G01J1/42
Filed: 1992-07-18
Abstract: The method involves sampling solid angle elements of a half- space to be measured and performing spectral analysis. The sampling is carried out using spherical coordinates and the spectral distribution is calculated for each solid angle element, using a spectrum detected by an imaging receiver. The spectra are evaluated by equal-energy analysis, normalised V-lambda curves, or cosine/sine theta calculation of spherical coordinates. A spectrometer and mirror may be used which are rotatably fixed and coupled to a high resolution CCD line receiver. USE/ADVANTAGE - For measuring intensity, spatial distribution and time variation of daylight/solar radiation, e.g. in meteorology, or UV measurements in chemistry. Many parameters may be measured using single appts.

Title: Method and arrangement for evaluating a value measured by a measuring convertor (transducer)
Inventor: HIRSCH HOLGER
IPC: G01R15/24
Filed: 1993-10-11
Abstract: A method and an arrangement are described for evaluating the value measured by a measuring convertor (SK) on the basis of the magneto-optical and/or electro-optical effect, with a (preferably polarisation-maintaining) optical fibre (LWL) as measuring sensor. The influencing magnetic or electric field causes rotation of the polarisation plane. The signals are opto-electronically converted and the rotation of the polarisation plane is determined using the evaluation arrangement (AT). The evaluation method consists of the steps: (R0) of setting the analysers (A1, A2) to an angle value which is symmetrical with respect to a fixed value (aO), (R1) normalising the measurement signal (Im1, Im2), (R2) combining the normalised signals (In1, In2) in a computational step, and (R3) integrating the combined signal (W2). In the case of the measuring arrangement with optical transfer of the measured signals, the opto-electrically converted signals (Im1, Im2) are corrected for attenuation and, before processing by the further steps (R2, R3), the attenuation-corrected signals are normalised (V2). <IMAGE>
