Conversely, a polarizer acts on an unpolarized beam or arbitrarily polarized beam to create one which is polarized. Unpolarized light can be described as a mixture of two independent oppositely polarized streams, each with half the intensity. [3] [4] Light is said to be partially polarized when there is more power in one of these streams than ...
A so-called depolarizer acts on a polarized beam to create one in which the polarization varies so rapidly across the beam that it may be ignored in the intended applications. Conversely, a polarizer acts on an unpolarized beam or arbitrarily polarized beam to create one which is polarized.
Beam – A measure of the width of the ship. There are two types: Beam, Overall (BOA), commonly referred to simply as Beam – The overall width of the ship measured at the widest point of the nominal waterline. Beam on Centerline (BOC) – Used for multihull vessels. The BOC for vessels is measured as follows: For a catamaran: the ...
Disregarding coherent wave superposition, any fully polarized, partially polarized, or unpolarized state of light can be represented by a Stokes vector (); and any optical element can be represented by a Mueller matrix (M).
A beam of unpolarized light can be thought of as containing a uniform mixture of linear polarizations at all possible angles. Since the average value of cos 2 θ {\displaystyle \cos ^{2}\theta } is 1/2, the transmission coefficient becomes
The beam of a ship is its width at its widest point. The maximum beam (B MAX) is the distance between planes passing through the outer sides of the ship, beam of the hull (B H) only includes permanently fixed parts of the hull, and beam at waterline (B WL) is the maximum width where the hull intersects the surface of the water. [1]
Areas where the degree of polarization is zero (the skylight is unpolarized), are known as neutral points. Here the Stokes parameters Q and U also equal zero by definition. The degree of polarization therefore increases with increasing distance from the neutral points. These conditions are met at a few defined locations on the sky.
