Abstract

Higher-order structure in the transparent optical polymer molding such as CD, DVD is enabled to be visualized and observed non-destructively and non-contactingly in a wide range of a microscopic level to a macroscopic level by applying light with specific wavelength to the transparent optical polymer molding from an incident optical system, and visualizing light with specific wavelength selected among a reflected wave and/or a transmitted wave of the light applied to the transparent optical polymer molding through an outgoing optical system.
