Dynamic range of the scalar and vector ZWFS using the gradient descent based reconstruction. For each configuration, 500 wavefronts are reconstructed consisting of 75 Zernike modes with a power law exponent between −1 and −3 and an RMS up to 250 nm. (a) and (b) Residual RMS for the scalar ZWFS using a monochromatic reconstruction for two different wavelengths (600, 1000 nm). (c) Residual RMS when employing the multi-wavelength reconstructor. (d), (e), and (f) Same results, but for a vector ZWFS.
