WebAug 4, 2024 · 1 Answer. A chopper by itself does not eliminate drift, a chopper and a highpass (or bandpass) filter eliminate drift. The point of "chopping" is to place the information bearing signal from being near dc having low frequency content to be at a convenient so-called carrier frequency (for a chopper the "carrier frequency" is the rate of …
WebOptical Choppers. Our optical choppers introduce a periodic interruption of the light path - useful for small optical signal detection schemes.
