OPTI 201R Fall 2009 2 OPTI 201R “is” all about: ! how light behaves “geometrically” (rays) ! calculations (predictions) of the “ideal” behavior of light (e.g. ideal shadows have sharp edges) ! ideal images ! image location, size, orientation, etc. ! visible light ! optical glass ! basic optical components (mirrors, lenses, prisms) ………………. . ! a (limited) introduction to basic optical instruments (more detail in OPTI 202R) ! THE foundation for understanding optical engineering OPTI 201R “is NOT” about: " how light behaves “physically” (EM waves) ! calculations (predictions) of the “real” behavior of light (e.g. actual shadows have fuzzy edges) " real images ! aberrations, diffractive effects, MTF, etc. " ultraviolet (UV), infrared (IR) energy " exotic materials used in the UV and IR " micro- or nano-sized optical components ………………. . " actual design of real-world optical instruments " photonic devices for the internet (modulators, switches, etc.) " real-world light sources " lasers!! " detectors, CCD’s " electronics, data acquistion " holography " interferometry " optical testing " …... ! future OPTI classes WILL cover these topics!!

OPTI 201R Fall 2009 3 Some Comments on the History of Geometrical Optics: # “The study of optics is as old as anything studied in physics.” (Nofziger) # The word “optics” originated in a book on visual perception (“Optica”) by Euclid over 2000 years ago, around 300 B.C. In it, he noted that light travels in straight lines, and described the Law of Reflection. # Archimedes (212 B.C.) tells of how the Greeks used “burning mirrors” to set Roman ships on fire. # Ptolemy of Alexandria (about A.D. 190) knew that glass and water had indices of refraction of 3/2 and 4/3, respectively. # “Geometrical Optics”—from the Greek word geometricus , meaning “according to geometry” and “characterized by straight lines, angles and circles.”
