The invention relates to a device (1) and a method (20) for determining a spectrum (X) of scattered radiation (S). The invention further relates to a method (70) for calculating the spectrum (X) and a method for compressing unstructured data (60) of known distribution. To be able to determine the spectrum (X) as precisely as possible and to derive from this the characteristics of materials that scatter laser pulses (P), the invention proposes that at least one characteristic of the laser pulse (P) is determined and that a spectrum analyser (5) is used for this. Frequencies (F) of laser pulses (P) and volumes (M) of back-scattered radiation (S) are combined into frequency and volume values (F', M') to calculate the spectrum (X). The most frequent data values are deleted from the data to compress the data (60). |
