Normalized reconstructed spectrum obtained along the reconstructed datacube in a fixed spatial position where the laser line was imaged (black trace). The red trace represents the normalized spectrum of the He-Ne source measured with the OSA.

PSNR versus the percentage of measurements used to reconstruct the 512×512 pixels images of the lit LED lamp with respect to their full dimensionality. All the PSNR values were calculated relatively to the 512×512 pixels image reconstructed using 100% of the measurements [see Fig. 4(b)].
