Patent ID: 8736839

Claim:
An optical measuring apparatus, comprising: a light source; a linear polarizer configured to linearly polarize light emitted from the light source; a polarized beam splitter configured to transmit the linearly polarized light to any one of a first optical path and a second optical path; a quarter wave plate configured to circularly polarize light transmitted through the first optical path from the polarized beam splitter and transmit the circularly polarized light to an object to be measured, and the quarter wave plate further configured to linearly polarize the circularly polarized light reflected from the object to be measured and transmit the linearly polarized reflected light to the second optical path of the polarized beam splitter; an objective lens configured to generate light having a plurality of different wavelengths by generating chromatic aberration in the circularly polarized light from the quarter wave plate; and a light receiver configured to produce image information of the object to be measured based on light from the second optical path.
