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.
Claims11
A method for visualizing higher-order structure of a transparent optical polymer molding comprising the steps of:
- applying light with a first specific range of wavelengths to the transparent optical polymer molding from an incident optical system;
- and
- visualizing light with a second specific range of wavelengths selected from reflected waves or transmitted waves of the light applied to said transparent optical polymer molding from the incident optical system by an outgoing optical system,
- wherein the first specific range of wavelengths and the second specific range of wavelengths are different from each other, and are selected to visualize higher order structure of the transparent optical polymer molding and thereby discern information regarding the structural integrity of the transparent optical polymer molding.
