I ordered the book by Mouroulis along with two other titles: "Binocular Vision and Stereopsis" (Oxford Psychology Series) by Ian Howard, and "Binocular Vision: Foundations and Applications" by R. W. Reading. I look forward to receiving and reading these titles. The book by (the late) Prof Howard seems particularly interesting. He was a professor at York University in Toronto. I myself graduated from University of Toronto and wanted to teach at York but it didn't work <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" />  Regarding binoculars with diverging fields, note that this does not necessarily imply that the observer's eyes are looking at a diverging angle. The observer looks at the image produced by the eyepiece and he sees two images that partially overlap (I am trying to understand this better myself). I also found this work <a href="http://spie.org/x39260.xml" target="_blank">http://spie.org/x39260.xml</a> which is along the same line as my thinking.</blockquote>
