Acousto-optic analyzer with dynamic signal compression |
摘要 |
An acousto-optic spectrum analyzer in which the dynamic range is effectively extended by detecting the frequency bands wherein the photo-detectors are saturated and providing a filter to suppress those frequencies. With this pre-filter, the entire spectrum appears to be within the dynamic range of the photo detectors. The actual spectrum can be reconstructed using the response of the suppression filter and the photo detector output.
