Polarization oflightnotes PDF

When something emits light, the waves produced usually have their oscillation moving at all different angles. You can have some oscillating left and right, up and down, at a 45-degree angle, or any angle imaginable. This is what we call unpolarized light, which means that all the light waves have different planes of oscillation. Polarized light is when light passes through a filter and the waves of light are limited to one plane of movement and the rest is absorbed, leaving polarized light to only have one plane of oscillation. The filter has tiny gaps in them that are all parallel to one another, as such only waves oscillating in parallel to the filter will pass through. This will decrease the intensity of the light passing through (intensity being the amount of light present), decreasing it dependant on the angle of the filter and if the light is polarised beforehand.

A resolution chart is a picture that has periodic objects in it that can be used to check the quality of optics. An old and famous resolution chart is the USAF 1951 test target pictured below.

There are several ways to use these charts. One way is to simply take a picture of them through the lens you’re trying to test. This works for lenses designed to image at finite conjugates (the distance from the lens to what it is aimed at is less than infinity). For infinite conjugate lenses, put the chart a the focus of a collimator and take a picture through the collimator. Or, for lenses designed for visual use, the lens is placed so that the target is at its rear focal plane and the inspector looks at the image (at infinity) formed by the lens.

Most questions will ask you to calculate the intensity of the light wave after it has passed through one of these filters, which can be done by multiplying the original intensity by the cos of the angle the filter from perpendicular to the floor. The formula for this is provided in the formula booklet, with the new and original intensity denoted by I and I0 respectively.

The advantages of resolution chart testing are that it is inexpensive and insensitive to vibrations. Disadvantages include the challenge of deciding whether a certain target is resolved or not, a decision which must be made by looking at the image through a camera and assessing by eye.

This resolution test chart was developed by the US Air Force to test lenses used to take pictures from airplanes. The National Bureau of Standards (now known as NIST) had their own resolution chart, and ISO has a chart designated 12233 for testing of electronic still cameras. A picture and description of the ISO chart is available here.
