摘 要:We present a new interferometric and holographic approach,named interferometry with doubled imaging area(IDIA),with which it is possible to double the camera field of view while performing off-axis interferometric imaging,without changing the imaging parameters,such as the magnification and the *** technique enables quantitative amplitude and phase imaging of wider samples without reducing the acquisition frame rate due to *** method is implemented using a compact interferometric module that connects to a regular digital camera,and is useful in a wide range of applications in which neither the field of view nor the acquisition rate can be ***,the IDIA principle allows doubling the off-axis interferometric field of view,which might be narrower than the camera field of view due to low-coherence *** demonstrate the proposed technique for scan-free quantitative optical thickness imaging of microscopic biological samples,including live neurons and a human sperm cell in rapid motion under high *** addition,we used the IDIA principle to perform non-destructive profilometry during a rapid lithography process of transparent structures.
