Fig. 2: Hyperspectral wavefront metrology.

a Comparison of the differential deviation angle induced by various prisms (2∘, 4∘ and 6∘) as a function of the wavelengths, using sequential measurements, single-shot multiplexed measurements and expected values. b Reconstructed tilted wavefronts at 640 nm comparing sequential reconstruction (S), single-shot multiplexed reconstruction (M), and the residual difference between them (R). c Comparison of the spectral defocus measured for two afocal systems (f1 = f2 = 50 mm) in NBK7 (in cyan) and SF11 (red) as a function of the wavelengths, with sequential measurements, single-shot multiplexed measurements and calculated expected values. d Reconstructed defocus wavefronts from the SF11 afocal system at 560 nm comparing sequential measurements (S), single-shot multiplexed (M), and the residual difference between them (R).
