  2. Euclid's Optics - Wikipedia

    en.wikipedia.org/wiki/Euclid's_Optics

    Similar to Euclid's much more famous work on geometry, Elements, Optics begins with a small number of definitions and postulates, which are then used to prove, by deductive reasoning, a body of geometric propositions about vision. The postulates in Optics are: Let it be assumed That rectilinear rays proceeding from the eye diverge indefinitely;

  3. Emission theory (vision) - Wikipedia

    en.wikipedia.org/wiki/Emission_theory_(vision)

    Some argued that Euclid's version of emission theory was purely metaphorical, highlighting mainly the geometrical relations between eyes and objects. The geometry of classical optics is equivalent no matter which direction light is considered to move because light is modeled by its path, not as a moving object. However, his theory of clarity of ...

  4. History of optics - Wikipedia

    en.wikipedia.org/wiki/History_of_optics

    The early writers discussed here treated vision more as a geometrical than as a physical, physiological, or psychological problem. The first known author of a treatise on geometrical optics was the geometer Euclid (c. 325 BC–265 BC). Euclid began his study of optics as he began his study of geometry, with a set of self-evident axioms.

  5. Visual perception - Wikipedia

    en.wikipedia.org/wiki/Visual_perception

    A refracted image was, however, seen by 'means of rays' as well, which came out of the eyes, traversed through the air, and after refraction, fell on the visible object which was sighted as the result of the movement of the rays from the eye. This theory was championed by scholars who were followers of Euclid's Optics and Ptolemy's Optics.

  6. 4th century BC Mo Di first mentions the camera obscura, a pin-hole camera. 3rd century BC Euclid is the first to write about reflection and refraction and notes that light travels in straight lines [4] 3rd century BC – The Baghdad Battery is dated from this period.

  7. Catoptrics - Wikipedia

    en.wikipedia.org/wiki/Catoptrics

    The Latin translation of Alhazen's (Ibn al-Haytham) main work, Book of Optics (Kitab al-Manazir), [6] exerted a great influence on Western science: for example, on the work of Roger Bacon, who cites him by name. [7] His research in catoptrics (the study of optical systems using mirrors) centred on spherical and parabolic mirrors and spherical ...
