Claim 12:
13. An all-in-focus imager comprising:
a camera including an image sensor;
an interferometer including:
a reference sensor having a plurality of reference-sensor pixels,
a reference mirror terminating a reference arm of the interferometer, and
a first beamsplitter configured to split, at a first beam-splitting interface, an input light beam into (i) a test optical-beam propagating from the first beam-splitting interface to an object, such that the object terminates a test arm of the interferometer and reflects the test optical-beam as a reflected optical-beam, and (ii) a reference beam propagating from the first beam-splitting interface to the reference mirror and from the reference mirror to the reference sensor;

a second beamsplitter configured to direct (i) a first part of the reflected optical-beam to the reference sensor and (ii) a second part of the reflected optical-beam to the camera; and
an actuator configured to change a length of the test arm by moving the object.
