摘要:
It is shown how a relatively simple representation of an absorbing multilayer can be obtained. This representation is used to derive some general properties of an absorbing multilayer and it is used to design a reflection interference filter, i.e. a filter which exhibits bandpass characteristics in reflection.

摘要:
This article deals with a theoretical analysis of two allied laser speckle interferometric techniques for measuring surface displacement and strain. One technique uses a Double Aperture Speckle Camera, and the other uses a similar interferometer called a Double Aperture Speckle Shearing Camera. These techniques, although developed elsewhere, had not been analysed for the cases when a generalized deformation of the surface under study takes place. Such an analysis was done and is presented here in an abbreviated form. It results in ‘new’ equations governing the formation of fringes by the two cameras. Various solution methods of these equations are outlined and discussed.

摘要:
A method is presented to determine contour maps of the first and the second derivatives of the deflection of an elastic bending plate. The deflection of a rough surface object is recorded once as a modulated diffraction grating. One of the diffracted waves is spatially filtered and brought into a shearing interferometer. The resultant shearing interferogram depicts contours of the first derivative of the deflection. The second derivative is obtained from the second modulated diffraction grating which is made with the interferogram of the first derivative. By recording the grating non-linearly, it is possible to obtain a substantial increase in the sensitivity of the interference fringes.

摘要:
In the visual masking effect, metacontrast, the perceived brightness of a flash of light is reduced by the presentation of a second flash in an adjacent region of the visual field. A metacontrast masking interaction between different colour mechanisms is examined in the present study. The spectral compositions and intensities of the stimuli are chosen so that the first (test) flash preferentially stimulates the blue-sensitive colour mechanism and the second (masking) flash preferentially stimulates the red-sensitive colour mechanism. Elevation in test-flash threshold is measured as a function of delay in presentation of the masking flash and an interaction effect shown to occur at both positive and negative masking-flash delays.
