摘要:
A spectrometer is described, especially for an optical coherence tomograph for detecting parameters of the human eye, with said spectrometer having an input for measurement radiation to be analyzed, fanning the measurement radiation spectrally out along a direction in a fan and guiding it onto a detector that extends along the direction and comprises a plurality of detector pixels that are sensitive to the measurement radiation, with the spectrometer having an adjusting element which can be adjusted in a controlled manner to adjust the relative position of the fan and the detector, thereby optimizing the incidence position of the fan on the detector, in which it is provided that the detector has at least two superimposed, adjacent pixel lines, and a control device is provided which reads out the superimposed pixels of a plurality of pixel lines in a combined manner for a spectral analysis of the measurement radiation in a pixel binning and evaluates signal differences between superimposed pixels to control the adjusting element and to center the incidence position of the fan at a right angle to the direction of the pixel lines.
