  • Patent number: 11125967
    Abstract: A system and method are provided for utilizing a focus state calibration object for determining calibration data for a variable focal length (VFL) lens system which includes a VFL lens (e.g., a tunable acoustic gradient lens). The calibration object includes a planar tilted pattern surface on which a set of focus state reference regions (FSRRs) are distributed (e.g., a tilted grating). The FSRRs have known geometric relationships relative to the planar tilted pattern surface and have known region relationships relative to one another. A plurality of camera images is acquired at different phase timings of the periodic modulation, and calibration data is determined based at least in part on analyzing the plurality of camera images. The determined calibration data indicates respective phase timings of the periodic modulation that correspond to respective effective focus positions of the VFL lens system.
