Message: <blockquote data-quote="Omid" data-source="post: 3627968" data-attributes="member: 16724">Hi Ed and Lars,Thank you very much for your recent notes and comments. @Ed: Please note that I don't intent my concept to "replace" wide-field binoculars, my idea can be combined with a wide field eyepiece. You are right in that additional peripheral visions may not be useful in birding but there are many applications that do benefit from enhanced peripheral vision (hunting, military, general field observations). You focus on your target at the center and at the same time remain aware of movements or other activity in a wide field of view.  In response to Lars comment I have to clarify that the two advantages I mentioned, would be best provided in separate products. I don't intend to combine reduced convergence and increased field of view in a single design (although it is possible to do so by making the invention in the form of an attachment that you connect to existing binoculars).A main reason I posted about my invention here is to do exactly what we are doing: making mental experiments and extrapolating from known concepts using our imagination. We have not fully explored the concept of "capturing an stereoscopic view" using divergent or convergent objective lenses and then "presenting said captured views" to the human eyes using convergent or divergent eyepieces. Note that these are two separate concepts. We can use similarities to 3D photography to predict what will happen in each case. Another comment in response to Lars: You call increasing the distance between objective lenses "true parallax" and tilting the view angle of the object lenses, "fake parallax". I would agree to some degree with this designation but we have not proven yet that the latter method would not produce enhanced 3D view. This method has actually been used for making 3D pictures using a single camera and it works (you can simply rotate the whole scene by a small angle and take a second picture with same camera position). Some amount of <a href="http://www.rmm3d.com/3d.encyclopedia/keystone/keystone.html" target="_blank">keystoning error</a> results from doing this but this is minimal at far distances (application 1) and can be corrected in application 2. Also see <a href="http://vfxio.com/PDFs/Parallel_vs_Converged.pdf" target="_blank">the great article here</a> which articulates the effects of having a convergent direction of view. So, lets continue the mind experiments and extrapolations a bit more. I am sure we might discover some interesting things... Regards,-Omid</blockquote>
