The two traditional systems are mirror -systems (
catoptrics ) and lens -systems (dioptrics ), although in the late twentieth century,
Kaynak: Image-forming optical systemlenses (dioptrics ), reflectors which use mirror s (
catoptrics ), and catadioptric telescopes which use both lenses and mirrors in combination.
Kaynak: Optical telescopeA catadioptric sensor is a visual sensor that contains mirrors (
catoptrics ) and lenses (dioptrics ), a combined catadioptric system .
Kaynak: Catadioptric sensorIbn al-Haytham 's work on
catoptrics in Book V of the Book of Optics contains the important Islamic mathematical problem known as
Kaynak: Alhazen's problemone where refraction and reflection are combined in an optical system, usually via lenses (dioptrics ) and curved mirror s (
catoptrics ).
