    Can any one help to achieve following.

    I have an object (anything like gold, glass etc), A pointed light source is thrown on the object. I want the data into the computer which are refracted from an object.

    I assume you mean a point light source?

    What degree of precision do you require? Just getting light into a
    computer can be handled with a US$10.00 webcam. A readily available
    prism, suitably interposed between the sample and the camera, will
    help determine the reflective and/or refractive properties of your
    sample. Many webcams can "see" in the infrared and infrared-capable
    prisms aren't hard to get or make.

    Determine what you want to know about the reflected/refracted light
    and that will help determine what kind of camera/prism combination you
    need.

    WHAT data?
    The fact that there is light/no light?
    Modulation of the light?
    That the reflector is glass and not gold?

    Would you please tell:

    - Do you want to measure the angle of reflection, or the percent of
    light intensity coming reflected,

    - Do you want to measure the same items of refraction (light going
    into the material)?

    - Do you want to measure the refractive index of the material?

    - Do you want to measure something else?
