Did I find an overlooked application for binocular luster (also known as retinal rivalry)?
Hello everyone, my name is Esdras Terranova, and I would like to ask for your help. I am interested in knowing whether anyone has proposed something similar to the following, as the sources I have read (1 and 2) do not mention it.
1)[Retinal Rivalry From Sterogram 8.4 (2004)](https://www.facebook.com/share/p/1AuDk4k4YD/)
2)[Binocular luster - A review](https://www.sciencedirect.com/.../pii/S0042698922000141...)
If one uses a linear polarizer viewer, like the one shown in photo 1, and goes outdoors, one can instantly detect sources of polarized light by perceiving binocular luster, as shown in photo 2 (more commonly known as retinal rivalry in the stereoscopic photography community).
Another application is that, if you go outdoors at night with a polarized flashlight, as shown in photo 3, you may more easily locate semi-buried metallic objects. In this case, the metallic objects function similarly to a silver screen used in stereoscopic projection, and again, detection occurs by means of binocular luster, as illustrated in photo 4.
If you are interested in reading a more detailed explanation of this proposition, you can find a copy at the following link:

Thank you in advance for any opinions, criticism, or help in providing a reference where something similar has already been reported.
