Simultaneous imaging and precision alignment of two millimeter wave antennas based on polarization-selective machine vision

A method for imaging and aligning antennas, said method comprising:

• configuring an overlay imaging aligner to include at least two antennas forming a straight line beam path with a polarization beam splitter therebetween, a polarization gate arranged perpendicularly to said straight line beam path, a non-polarizing beam splitter aligned with said polarization gate on an opposite side of said polarization beam splitter along a perpendicular straight line beam path, a beam dump and an alignment beam arranged on opposite side of said non-polarizing beam splitter, and at least one imaging lens and a common detector array;
• and
• aligning said at least two antennas via said overlay imaging aligner by overlaying simultaneous digital images associated with said at least two antennas on said common detector array by leveraging a spatial resolution of said digital optical images to align antenna components associated with said at least two antennas.
