    Curved diffraction?

    I found an exhaustive answer in the Geometrical Theory of Diffraction (GTD)! There is a substantial difference between edge and wedge: an edge it's i.e. a border of a polygon and the diffraction caused by it it's always a straight line. A Wedge, it's an edge between two polygons, and the...

    Laser into camera lens

    What is the pattern made of balls? https://www.youtube.com/watch?v=KrUhKQxOPx0 I have some hypotesis: Something related to the CCD, a diffraction pattern caused by some dirt on the lens, or, but i think it's absurd, the Bravais lattice of the lens? I'm very curious!

    Curved diffraction?

    I'm doing some experiences with a laser about diffraction caused by an edge, and I have some question to ask. Unfortunately, I've found very few literature (almost nothing) about diffraction caused by an EDGE. Everyone explains well diffraction caused by slits; someone explains diffraction...

    A radiometry problem, please help! :-)

    Ok... maybe i've solved it but i still have some doubt. The answer should be: It's 400(pi) W/m^2 in both cases of 45° and 0° because the surface is Lambertian. The irradiance on a point of the surface is 1000(pi) W/m^2, then the reflected radiosity is 400(pi) in every direction because it's...

    A radiometry problem, please help! :-)

    The exercise i have is as follows: A flat plate (measuring 0.5 meter by 0.5 meter) is placed on the highest mountain in the landscape, exactly horizontal. It is a cloudy day, such that the sky has a uniform radiance of 1000 W/ m^2 sr. The plate has a uniform Lambertian reflectance p=0.4...
