Fourier Analysis of Slow and Fast Image Propagation through Single and Coupled Image Resonators
Figure 6
(a) Experimental setup for time- and space-resolved image propagation through the image resonator. Light pulses of 40 ns duration passed through an image mask and an image resonator system. The reflected images were sent to the streak camera using a half mirror (HF) to analyze time- and space-resolved reflected images. (b) (A) and (b) (B) show the reflected image for the off-resonance and on-resonance conditions, respectively. (b) (C) is the experimental observation of the temporal profiles of the reflected image. The dashed black curve is at the center of the off-resonance image; the solid blue and red curves are at the edge region and center region of the on-resonance image, respectively. (b) (D) is the cross-sectional profile of image (b) (B). The notations 1, 2, and 3 indicate the earlier, intermediate, and later times of the image, respectively.
