Abstract

This supplementary material has five sections. The first shows the Snell’s window height is not a factor in our design and can be chosen arbitrarily (if a lenslet is present, it must at least cover the lenslet). The second discusses, in terms of lightfields, the types of optics that allow distant scene convolution. The third shows an imaging example of Snell’s window on our prototype. The fourth explains how our designs differ from previous work on optical filtering of planar scenes. The fifth discusses aperture thickness vignetting of a design’s angular support. 1 Snell’s window height In the paper, we assumed the height of the Snell’s window is exactly the image distance of the embedded lens. Here we show two derivations, one with this assumption and one without. Since the two equations we derive are equal, the height of the refractive material does not matter and we can set it to whatever value we choose. 1.1 Lenslet in a Snell’s window as in the paper In Figure 1 we show the setup as in the paper. Our approach is to derive an equation for the value of the exterior angle ω in terms of the exterior unrefracted angles in the design. We show this equation is identical in the next section, which is derived from the general case. Consider the right angles containing θ ′ 1, θ ′ 2 and θ ′. The tangents of these angles + d 2 − d
