Fig. 5 — (a) Square wave modulation contrast obtained by applying the DT algorithm on the average of 4 frames and the proposed SR method. This is compared with imaging through the 1.92X GRIN lens optical system with no imaging bundle. Image of USAF target showing all elements of Groups 8 and 9, reconstructed using the proposed method where fiber shifts are generated using (b) PZT scanner and (c) motorized translation stage. (d) Shows 2-D graph of the intensities of pixels along a line segment on G8, E2-6. Scale bar is 10 µm.
