Zero Drift Infrared Radiation Thermometer Using Chopper Stabilised Pre-Amplifier

Zero Drift Infrared Radiation Thermometer Using Chopper Stabilised Pre-Amplifier

A zero-drift, mid–wave infrared (MWIR) thermometer constructed using a chopper stabilised operational amplifier (op-amp) was compared against an identical thermometer that utilised a precision op-amp. The chopper stabilised op-amp resulted in a zero-drift infrared radiation thermometer (IRT) with ap...
