Fourier Analysis of Slow and Fast Image Propagation through Single and Coupled Image Resonators
Figure 3
(a) Original image injected into the cavity. (b) Fourier-transformed input image. The full width at half maximum of the Fourier image is mm−1. (c)–(e) Reflected images obtained using continuous wave input light for under (, , mm−1), critical (, , mm−1), and over coupling (, , mm−1) conditions, respectively. (f) and (g) Reflected output images from the coupled image resonator (, , , cm, cm, mm−1, MHz) using a continuous wave input beam and temporal pulses of 25 ns MHz, respectively.
