Abstract:
1. A method for a controller in a laser system to compensate a variability of an analog-to-digital converter (ADC) in the laser system, the method comprising: receiving a temperature signal corresponding to a temperature of a laser; and determining a compensated digital output signal based on at least the temperature signal and a digital output signal from the ADC, the compensated digital output signal compensating for the variability of the ADC, said determining a compensated digital output signal comprising a step selected from the group consisting of (1) looking up the compensated digital output signal based on at least the temperature signal and the digital output signal, and (2) calculating the compensated digital output signal based on at least the temperature signal and the digital output signal; receiving a supply voltage signal corresponding to a supply voltage to the laser system; and wherein said looking up the compensated digital signal and said calculating the compensated digital signal are further based on the supply voltage signal.
