Arrangement for rapid locally resolved flat surface spectroscopic analysis or imaging has flat raster array of pinholes turned about acute angle relative to spectral axis on detector matrix which fills up with elongated su-matrices

摘要

The arrangement has a flat raster array (5) of pinholes with optical copying system (6), a flat surface detector matrix (9) in the detection ray path and with means (7) for lateral spectral splitting and focussing means (9). The flat array is turned about an acute angle relative to the spectral axis on the detector matrix and through rotation a connecting line of pinholes when projected includes an acute angle with the spectral axis and the detector matrix is filled up more or less completely with elongated submatrices (9a,9b) arranged parallel to the spectral axis but not overlapping. Independent claim describes method for 3-D detection by spectroscopy with chromatic calibration producing a single at least partially spectrally defined reference light bundle.
