Fresnel Relations and the Sensitivity of a Camera

[ecastro]

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.

Thank you. Although there is no wavelength dependency on the process, I understood more about the deconvolution and convolution of images.
