<p><P>PROBLEM TO BE SOLVED: To provide an optical system capable of calculating the thickness of a scattering medium. <P>SOLUTION: This optical system includes a light sending section that sends light to an object having a scattering medium and a lower medium positioned below the scattering medium, where the scattering medium scatters light and the lower medium feeds back polarized light in response to light incident thereon, a light receiving section that receives a light that is sent from the light sending section and then scattered by the scattering medium and a light from the lower medium, and a thickness calculating section that calculates a thickness of the scattering medium, by referring to at least one of a non-polarization component and a polarization component of the light received by the light receiving section. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
