Diffraction-pattern Sentence Examples

diffraction-pattern
• If the aperture be increased, not only is the total brightness over the focal plane increased with it, but there is also a concentration of the diffraction pattern.

• The contraction of the diffraction pattern with increase of aperture is of fundamental importance in connexion with the resolving power of optical instruments.

• According to common optics, where images are absolute, the diffraction pattern is supposed to be infinitely small, and two radiant points, however near together, form separated images.

• If the image of the line be =o, the intensity at any point E, n of the diffraction pattern may be represented by ?2a2t2 S A2f2 the same law as obtains for a luminous point when horizontal directions are alone considered.

• By this procedure the width of the central band in the diffraction pattern is halved, and so far an advantage is attained.

• In these expressions we are to replace p by ks/f, or rather, since the diffraction pattern is symmetrical, by kr/f, where r is the distance of any point in the focal plane from the centre of the system.

• The first dark ring in the diffraction pattern of the complete circular aperture occurs when r/f = 1.2197 XO /2R (15).

• The diffraction pattern is therefore that due to a single aperture, merely brightened n times.

• In observing the bands he received them at first upon a screen of finely ground glass, upon which a magnifying lens was focused; but it soon appeared that the ground glass could be dispensed with, the diffraction pattern being viewed in the same way as the image formed by the object-glass of a telescope is viewed through the eye-piece.

• With fairly homogeneous light the diffraction pattern may be observed at a distance, varying with the width of the slit from about the length of the collimator to one quarter of that length.

• This window shows a simulated TEM diffraction pattern for the wurtzite structure, colour-coded to show the phase of diffracted intensity.

• What else can we say about the diffraction pattern from a protein crystal?

• The linear dimension of the diffraction pattern is inversely as that of the aperture, and the brightness at corresponding points is as the square of the area of aperture.

• Sophisticated mathematical techniques are then used to analyze the diffraction pattern.
