From the article:

Ordinarily, an expensive notch filter would be used which is cost prohibitive for most average people. My system avoids this cost by using two less expensive edge filters which when combined in the correct manner provide the same benefit as the notch filter...at the minimal cost of a little extra computing time.

If the goal is to cancel the incident light "carrier" frequency, couldn't this also be done interferometrically, just using mirrors and beam splitters?
