摘要： A stress measurement method is provided of the present disclosure. The stress measurement method includes an image capturing procedure, a phase shift calculation procedure, an isochromatic intensifying procedure and a transformation procedure. The image capturing procedure is used to capture four light intensity images with four different phase angles of a sample. The phase shift calculation procedure is used to obtain an isochromatic retardation of the sample when the four light intensity images have sufficient light intensity values. The isochromatic intensifying procedure is used to calculate two enhanced light intensity values, the background of intensified isochromatic light intensity value and the amplitude of intensified isochromatic light intensity value to obtain an isochromatic retardation when the sample is in a low stress condition. The transformation procedure is used to transform the isochromatic retardation to a stress value of the sample.

摘要： A method for controlling a printing system adapted to print images on a web of media that is photoelastic and at least partially transparent. One or more printing stations are used deposit a pattern of printing material on a web of media travelling along a web transport path, thereby producing a printed image. A pattern of stress in the web of media is measured using one or more photoelastic measurement devices disposed along the web transport path, wherein the pattern of stress is at least partially induced by the deposited printing material. The measured pattern of stress is analyzed to detect the presence of one or more print defects, and a at least one aspect of the printing system is controlled responsive to detecting a print defect.

摘要： Methods of capturing improved-contrast mode spectra of a double ion-exchanged (DIOX) glass sample using prism coupling of index np. The DIOX glass sample has a refractive index profile with a first region adjacent the surface that satisfies 0.0005 ≤  λ n   n  x  ≤ 0.0009 , where λ is a wavelength of measuring light. The prism-sample interface includes an interfacing liquid of index nf that differs from np by no more than 0.03, and that can exceed np. The mode spectra have a contrast that is higher than that obtained by conventional prism coupling by using gradient illumination or partially blocked illumination that reduces the amount of background reflected light from the coupling prism. The improved-contrast mode spectra can be processed using conventional means to determine at least one stress characteristic of the DIOX glass sample.
