Abstract

Described is camera focusing including lens centration estimation using variable focal length phased metalenses. Camera modular alignment and test (CMAT) equipment checks the modular transfer function (MTF) performance of lenses and an image sensor. The CMAT equipment positions a variable focal length phased metalens between the lenses and the image sensor. The metalens includes multiple segments that provide a variable focus depending on distance and angle from boresight of the image sensor. By measuring optical characteristics of the lenses at two opposing segments of the metalens, defocusing effects and a lens centration tilt vector can be computed. Repositioning the lenses to align the centration tilt vector with the boresight of the image sensor improves the MTF performance. A final camera assembly with lenses in precise alignment with the image sensor can be produced, which may improve production output by increasing pass rate at an end of line tester.
