polarized and non polarized images

[EDIT: 20110518 17:57 EDT - merge duplicate, reformat - WDR]

[First version]

Use images taken under such conditions:

• Object is lit from the front by non npolarized light and the image acquired when lightreflected from the object captured by the camera and polarizer, image ’L2S11.jpg’.
• Object is lit from the front by polarized light and the image acquired when lightreflected from the object passes the analyzer placed in front of the camera, image’L2S12.jpg’.

Related questions:

• Find out what parts of the image of the circuit board were emphasized and why?
• Calculate the changes of S/N in the parts of the images for both cases?

Explanation should include:

• Describing of the optical scheme used?
• What information from polarized illumination with analyzer can be extracted?

[Second version]

two images one with polarizer and other one without polarizer. what parts of the image is emphasized and why?

calculate the changes in S/N for parts of image for both cases?

Description of optical scheme used?

what information from polarized illumination with analyser can be extracted?
