Abstract : The patent concerns an optical divider point assembly for harmonic spectrum analysis having a cylindrical drum with one or more sets of spiral lines. Each set originates at a point and diverges in equal separation and rotates within a housing having an elongated slot parallel to the drum axis to project reflected light from the spiral lines onto a supporting surface of frequency spectrums through a beam splitter plate to match the points of reflected light with frequency harmonics at the points of virtual image formation to identify same. The matched position is read out of a potentiometer position having its adjustable tap mechanically connected to rotate with the drum.
