Claim 18:
19. A head-mounted device, comprising:
a head-mounted support structure;
a first optical component supported by the head-mounted support structure;
a second optical component supported by the head-mounted support structure;
an optical interferometer sensor configured to measure misalignment between the first and second optical components, wherein the optical interferometer sensor comprises a beam splitter that splits light into first and second light beams, and wherein the optical interferometer sensor is configured to measure a relative phase of the first and second light beams; and
control circuitry configured to compensate for the misalignment between the first and second optical components measured with the optical interferometer sensor by applying an image warping to at least one of: a first image associated with the first optical component and a second image associated with the second optical component.
