A method and system for calibrating an optical tomographic imaging system that is configured to execute time-series optical measurements of a target's response to incident optical energy is presented. An electro-active device that is configured to be electronically modulated to control the electro-active device's opacity is embedded in a dense scattering medium. A known hemodynamic response pattern is selected and at least one wavelength of optical energy that produces the known hemodynamic response pattern is determined. A wavelength-dependent driving voltage function is then computed. A voltage is then applied to the electro-active device according to the wavelength-dependent driving voltage function. Optical energy is then transmitted to the scattering medium at the at least one wavelength and a hemodynamic response for the target is determined. The known hemodynamic response pattern and the determined hemodynamic response pattern are then compared. |
