Claim 19:
20. The all-in-focus imager of claim 12, further comprising:
a processor communicatively coupled to the camera, the reference sensor, and the actuator; and
memory storing non-transitory computer-readable instructions that, when executed by the processor, control the processor to:
for each of a plurality of surface-regions of the object, determine a corresponding image-sensor pixel group of the camera illuminated by light propagating from the surface-region of the object via a lens of the camera, all locations within each surface region being closest to a respective object plane of a plurality of object planes each displaced from and parallel to an in-focus object-plane of the camera;
after the step of determining and for each surface-region:
change a distance between the object and the lens such that the surface region intersects the in-focus object-plane and the lens forms an in-focus surface-region image on the corresponding image-sensor pixel group,
capture, with the corresponding image-sensor pixel group, the in-focus surface-region image of the surface-region; and; and

combine a plurality of in-focus surface-region images, obtained by performing said capturing for each of the plurality of surface-regions, to yield an all-in-focus image of the object.
