Fresnel Relations and the Sensitivity of a Camera

  1. Jun 7, 2015 #1
    Reflectance, according to the Fresnel Relations, is given by

    ##R \equiv \frac{I_r}{I_i}##,

    and Transmittance is

    ##T = \frac{I_t \cos \theta_t}{I_i \cos \theta_i}##.

    Do these values depend on the wavelength of light? For example, if I have a beam of white light rather than a monochromatic one, and I need the Transmittance and Reflectance of a specific wavelength.

    Second, I need the value of the Reflectance and Transmittance of light with a specific wavelength be multiplied with a camera's sensitivity. But I only have the ISO value of the camera, I don't know what to do with it.

    Lastly, what is the technique called in Image Processing where a gray image is subjected to deconvolution and convolution procedures to see the image on different wavelengths?

    Thank you in advance.
