H-
small laser is turned to emit horizontally polarized light
-H
small analyzer polarizer in front of camera is oriented to
admit only horizontally polarized light
V-
small laser is turned to emit vertically polarized light
-V
small analyzer polarizer in front of camera is oriented to admit
only vertically polarized light
P-
small laser is turned to emit light polarized at 45 degrees from
the horizontal
-P
small analyzer polarizer in front of camera is oriented to admit
only light polarized at 45 degrees fromthe horizontal
R-
small a quarter wave plate is placed directly in front of the laser
to create right-hand circularly polarized light
-R
small a quarter-wave plate is used as an analyzer optic
In this manner, the combination ``HV'' would represent the picture
taken with a horizontally polarized laser and an analyzer directly in
front of the camera oriented to allow only vertically polarized light
to pass. The basic mathematical functions (i.e. addition,
subtraction, multiplication) are done using the Scion image analysis
software. To create some matrix elements it is necessary to subtract
an entire other element, which is done solely to simplify the
equations.
