a Schematic of photon propagation in biological tissues with high and low light absorption, and the corresponding imaging effects. b The absorption spectrum of water within 700–2300 nm27. c Simulated images within 1200–1300, 1300–1400, 1400-1500, 1500–1700, 1700–1880, and 1880–2080 nm, through routine biological tissue of 1 mm thickness, where the absorption coefficient of water was considered as the tissue absorption coefficient and the setting of tissue scattering coefficient could be found in the “Methods” section. d SBR analysis of the simulation results. n = 3 positions were randomly selected for analysis, data are presented as mean ± SD. e The structure similarity index measure (SSIM) analysis of the simulation results.
