摘要:

A new method is given for evaluating the intensity in the multiple beam interference pattern in reflection based on considering the interfering beams as two vectors only and summing them diagrammatically. The method is applied to calculate the effect on the intensity distribution of modulating the phase of the first beam. The phase modulation is achieved by introducing a thin silver film of predetermined phase shift in transmission.

摘要:

In this paper the problem of similarity between an optical object and its image for imaging with partially coherent quasi-monochromatic light according to thenth-order correlation is formulated. This problem leads to a non-linear homogeneous integral equation which is studied as a special case of algebraic integral equations or, on the other hand, by the method of successive approximation. It is shown that under certain assumptions there exists at most a countably infinite set of structures imaged similarly. Only a finite number of structures can be imaged similarly with sufficiently large intensity.

摘要:

On décrit une méthode permettant d'obtenir rapidement la forme des images données par un réseau concave à deux dimensions. Les calculs ont été faits avec un ordinateur IBM 1620 pour deux types de monochromateurs couramment utilisés dans l'ultra-violet lointain. On compare la forme des images obtenues suivant la longueur d'onde, la largeur utile du réseau et la largeur de la fente d'entrée. On montre que d'une manière générale la luminosité est une fonction linéaire de la largeur du réseau.

摘要:

The radiation pattern of a circular aperture illuminated both uniformly and non-uniformly by partially coherent light is calculated in the diffraction limit. Furthermore, the angular resolution of a circular lens is examined for four reasonable correlation functions. Also the effects of the parameters—partial coherence, misalignment, and non-uniform illumination—on the diffraction pattern of a double slit are considered for a particular mathematical model of the radiation field. The results of this analysis are used to discuss the the use of diffraction experiments in the study of the coherence properties of light.

摘要:

The theory of image formation in optical instruments in partially coherent illumination is applied to calculate the luminance distribution in the image of an opaque straight-edge; experimental and theoretical results are compared. The first and the second derivative of luminance with respect to distance are given. The extension of the method to include edges with contrast less than one, finite gratings and any staircase-like objects is outlined.

摘要:

The study of the effect of chromatic adaptation on the appearance of colours is furthered by the application of the binocular matching technique to seven illuminants radiating in different regions of the spectrum. The invariants are calculated and their distribution is discussed.
