A method, apparatus and system for enhanced OCT measurement is described. The invention provides for using an OCT system with two or more optical sources with different wavelengths from each other to analyze tissue and measure scattering characteristics and absorption properties of a target. Embodiments include using multiple differential states: multiple wavelengths multiple pressure wave environments and multiple temperatures. Embodiments also include using temperature stabilization and speckle reduction by means of subjecting the target to one or more pressure waves.
