Fig. 1. Overview of the IMSS-SAI framework. The target is illuminated by a tri-wavelength fiber laser, and the Fourier spectrum is formed at the aperture plane of the camera array.

Fig. 2. Flow chart of the iteration reconstruction of IMSS-SAI.

Fig. 3. Reconstructions of the USAF resolution chart and the coin. (a1), (a2) The spectrum information and corresponding low-resolution image captured by a single camera. (b1), (b2) The expanded spectrum range and the reconstructed result by IMSS-SAI, with the corresponding line profile of group 0 shown at the bottom. (c1)–(c3) The low-resolution image of the coin and the regions of interest. (d1)–(d3) The averaging result and the regions of interest. (e1)–(e3) The recovery result and the regions of interest.

Fig. 4. Experimental results of IMSS-SAI on far-field targets. (a1)–(d1) The low-resolution images and the corresponding regions of interest. (a2)–(d2) The averaging results and corresponding regions of interest. (a3)–(d3) The recovery results and corresponding regions of interest.

Fig. 5. Constructed music box dynamic rotating imaging results. (a) Comparison of the recorded low-resolution image (under F-number 12) with the predicted super-resolved image. (b1)–(b4) Raw image, averaging result, recovery result, and denoising result of the region of interest 1, respectively. (c1)–(c4) Raw image, averaging result, recovery result, and denoising result of the region of the interest 2, respectively. (d1)–(d6) The instantaneous frames of the eagle emblem captured every 0.5 s (15 frames) with IMSS-SAI.
