Abstract
An optical scanning system uses a low-resolution scanning operation, to automatically adjust the sensitivity of the system. The system performs a low-resolution scanning operation by scanning a line, automatically and iteratively setting the levels of excitation signal power and detector gain, skipping a plurality of lines and scanning a next line, adjusting the levels as appropriate, skipping a plurality of lines and scanning a next line, and so forth. After the system sensitivities have been set, the calibrated system then scans all the lines of the sample to collect data. The calibrated system thus scans for the first time the lines that were skipped during the low resolution scanning operation.
