Abstract：In order to obtain a higher signal to noise ratio of the optical signal, especially from the depth of interest, the equivalent signal to noise ratio (ESNR) was defined as the proportion of the photons from the DOI to the total photons the detector got to evaluate the best source and detector (SD) separation.The Monte-Carlo(MC)simulation was used to establish a multi brain layer model to analyze the distribution of the ESNR along the radial direction for different DOIs and several basic brain optical and structu reparameters.It provides an important reference and new thin king for the brain imagingin the near infrared.
