摘要
An integrated imaging element for an interferometer generates at least one image that includes multiple interference portions with different relative phase shifts interleaved in a pattern having a high spatial frequency in the image. The interleaved pattern is at least partially determined by the pattern of a high density polarizing array used in the integrated imaging element. In various embodiments, the multiple interference portions are interleaved in a checkerboard pattern across the entire surface of a detector device. As a result, various non-common mode errors present in various interferometers that generate separate non-interleaved images for each relative phase are reduced or eliminated because multiple phase-shifted interference image information for a small region of an object is provided within a small region on the detector device.
