Experiments with Polarized Light at Slit and Double-Slit

 


Experiments at slit with varied polarized light show only at very narrow slit-widths and high diffraction-orders a noticeable influence. This is explained by Newton's demonstration of localization of bent light near the edge. The experiment by Fresnel is repeated where a double-slit with right and left circular polarized light in the single slits yields no interferences. This result was confirmed but with a polarizing-filter in front of the catch-up plane appeared the interference-figure of double-slit, whereat its fringes move by turning the filter. Therefore without polarizing-filter only a blurred figure is originated.

Figure 1. Examples for influence of polarization of light in diffraction at slit. The light of a Ne-He-laser HNA 50 passed a rotator and was focused on the illumination-slit 0.05 mm slit-width. The with an objective f' = 35 cm parallel directed light strikes the diffraction-slit.
a: 1 mm slit-width in 1 m distance,
b: 0.03 mm slit-width in 0.065 m distance.
Photometer-curves:

L - light-source, a mercury high-pressure lamp HBO 100; C - Condenser; F - green-filter; M -mikroscope-objektive; ID - illumentation circular-opening 0.1 mm; Le 1 - lens f' = 1 m; PF 1 - polarization-filter Zeiss-Bernotar in 45-position; DS - double-slit with 1.5 mm stick and ever one λ /4-plate of glimmer, where the direction of extinction in or 90 to the slits were cut; Le 2 - lens f' = 2 m; PF 2 - polarization-filter, rotating before the camera; P - camera-body of a single-lens reflex-miniature camera.

Illuminated with parallel mercury light with green-filter. Negatives are tree-fold enlarged. Distance: a: 25 mm, b: 125 mm, c = 275 mm, d = 720 mm..

Discussion


Newton [1] book III observation 5 had shown that bent light comes only out of a small surrounding of the edge. Nieke [12], [13] and [14] showed particulars to this fact, light comes out of a surrounding smaller than 0.1 mm of every edge, independent of slit-width. With it is explicable the constant difference independent of slit-width in figure 2: only on bent light exists an influence of direction of polarization, in the middle of the slit passing light is not influenced. Figure 1 show that bent light is not stricken equal but ever the order of bent light the stronger the influence of polarization. Newton [1] III, query 1 supposed that stronger bent light passed near the edge. The stronger influence of polarization can also be connected with it. The change of preference-direction by Bois a. Rubens [10] indicated in optical radiation for an influence of structure of photons and first in Hertz's radiation for a matter-interaction.
According to these results opposite circular polarized light shows only therefore not the diffraction-figure of double-slit because the single components of inter-direction of diffraction-fringes lay side by side and so no diffraction-figure is visible.
Moreover already Fresnel was known that about a plate of glass brought in a light-path of one slit shifts the diffraction-figure of the double-slit.
