Claim:
1. A sweeping laser system comprising: a semiconductor laser source that is operable to discretely output radiation over a range of wavelengths in a radiation sweep along a number of wavelength points based on an input signal comprising a group of controlled parameters, wherein a timescale of a period of the radiation sweep is nanoseconds or microseconds and variations in uncontrolled parameters occurring during the sweep have a direct effect on the semiconductor laser source and the electromagnetic radiation output by the semiconductor laser source; a laser control unit operatively coupled to the semiconductor laser source, wherein the semiconductor laser source is configured to receive the input signal from the laser control unit to discretely change the radiation over the range of wavelengths based on the input signal; and a sweep performance monitoring device configured to detect data associated with at least one physical property associated with radiation over the range of wavelengths; and a processor to configure the laser control unit to adjust the input signal to the semiconductor laser source at one or more points in the radiation sweep in order to: wherein each point in the one or more points is adjusted utilizing a plurality of points from any portion in the radiation sweep and the sweep performance monitoring device is coupled to the processor.
