Graduate Courses in Optical Science and Engineering (OSE) Below are listed all the graduate courses in optics at UAH. Currently, there are 33 offerings covering the full gamut of modern optics. Graduate courses in optics are designated as OSE, PH and/or EE. This reflects the sponsorship of the course. Multiple designations indicate joint responsibility. The OSE courses are listed with full descriptions below. This is followed by a listing of courses whose full descriptions can be found in this catalog under the appropriate department heading.
