MULTI-PARAMETER CALCULATION VIA MODAL POWER MEASUREMENTS

Abstract:

A method includes determining an angle of a major axis of an imaged distant sub-diffraction object by obtaining a ratio of measured power of two different optical modes, obtaining power measurements at the angle for three different optical modes, and comparing the power measurements to a catalog of power measurements from one or more known reference objects of known dimensions to determine values for the major axis, a minor axis, and a convexity.
