Optical Phantom Development for Skin Measurement

We have successfully developed and manufactured a three-layered scattering agent-embedded optical phantom in order to mimic the structural and optical properties of the human skin. Characterization is done for the optical phantom. The widths of the individual layers can be controlled within +/-10% of the designed thickness. The refractive indices, scattering and absorption coefficients are close to the human skin. The scattering agents in the optical phantom act as point sources which can be used to measure point spread function (PSF). Such a device can be useful for applications that require an accurate optical model for human skin evaluation such as Optical Coherence Tomography (OCT) and Reflectance Confocal Microscopy (RCM) in cosmetics and dermatological diagnostics.
