Comparison between MM-OCE and indentation measurements performed on homogeneous PDMS phantoms. (a) Young’s modulus values obtained by both methods showed a good linear correlation (Pearson’s r = 0.965) and agreement (slope = 1.047, with a negligible offset = −1.325 kPa) with each other. (b) Bland-Altman plot also showed a good agreement between the two measurements (mean difference = 0.558 kPa). Sample size N = 16.
