Grating induction
When choosing a grating it is important to specify the wavelength range, blaze wavelength (which is the wavelength in the diffracted spectrum with the highest efficiency), and blaze … See more Edmund Optics® offers a wide range of diffraction gratings spanning the entire range of options discussed above. See more WebIt is suggested that grating induction is perceived when subjects attend to local contrast differences, while phantom visibility is facilitated when attention is captured by the more global aspects of the stimulus. © 1999 Elsevier Science Ltd.

WebGrating induction (McCourt, 1982) produces a conspicuous sinusoidal brightness modulation (i.e., a grating) in a horizontal homogeneous test field inserted into a … WebThe McCollough effect is a phenomenon of human visual perception in which colorless gratings appear colored contingent on the orientation of the gratings. It is an aftereffect requiring a period of induction to produce it. For example, if someone alternately looks at a red horizontal grating and a green vertical grating for a few minutes, a black-and-white …
WebAug 1, 1985 · Among the many attractive features of grating induction is the possibility of obtaining a measure of its magnitude by canceling it with a real grating of opposite phase. WebThe material provides greater strength, reliability, and flexibility, qualities that make it well-suited for use in critical structures, such as stairs, ducting, roofing, and more. Agriculture …
WebTop left: grating induction stimulus. The horizontal gray stripe running through the middle of the luminance grating is uniform yet appears modulated in brightness due to simultaneous brightness contrast. Bottom middle: an adjustable grating with similar spatial dimensions to the induced grating can be used to match its apparent contrast. WebTo assess the influence of edge sharpness in the expression of the grating induction effect, induction magnitude was measured, by using both cancelling and contrast …
