í Measuring the Angle of Polarization and the Light Intensity
u Position the optical probe so it is pointing at the penlight and picking
up the maximum light intensity.
u Prepare the Optical Measurement Setup and start the measurement. Rotate the polarizer
90 degrees at a constant speed, every 20 seconds.
í Measuring Brewsters Angle
u The light intensity is displayed on the calculator.
u From an angle determined using the protractor, shine the penlight beam onto the glass.
u Position the optical probe so it is pointing at the light beam and picking up the maximum
light intensity.
u Rotate the polarizer until the polarization direction is that where the light intensity is the
greatest.
u Measure the polarizing direction of the reflected light.
u Measure the polarizing direction of the refracted light.
u Determine the angle of the penlight beam that satisfies the condition expression of
Brewsters angle.
í Calculator Operation
u Prepare for measurement of light intensity using the optical probe, which will let you
determine the angle of polarization.
Using E-CON
Using a Calculator Program
Find the applicable program in the Program Library (P.2-16-2), input it into your calculator,
and then run it.
u This displays a graph that shows changes in light intensity as the polarizer is rotated.
L : Light Intensity
t(s): Time
u Perform the following operation to measure Brewster’s angle.
u Find the applicable program (Light Multi Meter) in the Program Library (P.2-16-2), input it
into your calculator, and then run it to measure light intensity.

Measurement
u Investigate changes in Brewster’s angle using materials other than glass.
u The 3D effect is possible because of the slight difference between how an object is
viewed by the left and right eyes. Consider how 3D imaging technology uses the
characteristics of light polarization to achieve its effects.
To obtain an accurate picture of changes in polarizer angle and light intensity, it is a good idea to
graph light intensity at various angles.
