    Abstract: Systems, devices, and methods including a first band-pass filter configured to receive and filter a detector signal where the first band-pass filter has a central frequency of 2f; a second band-pass filter configured to receive and filter the detector signal where the second band-pass filter has a central frequency of 1f; a first logarithmic amplifier (Log Amp) configured to apply the filtered detector signal from the first band-pass filter; a second Log Amp configured to apply the filtered detector signal from the second band-pass filter; a differential amplifier configured to subtract the applied signal from the first Log Amp from the applied signal from the second Log Amp; and an Anti-Log Amplifier configured to determine an inverse logarithm of the subtracted signal from the differential amplifier.
