Patent number: 8159753Abstract: An optical lens which, in a controlled manner, and without altering either the resolution or luminous capture, helps to extend the depth of field of any other optical system. The optical lens of the present invention is composed of two optical lenses that form a pair. Each of the lenses of the pair produces a change of optical path with a symmetrical distribution. If there is no relative displacement, the lenses of the pair generate an optical path difference equal to zero. When there is relative displacement, the lenses of the pair generate a change of optical path with asymmetric distribution, which helps to extend the depth of field without reducing either the resolution or luminous capture. The optical lens of this invention, in the form of an optical pair, serves any other optical system to capture images without loss of modulation, but with attenuated modulation which can be retrieved with digital processing algorithms known in the art.Type: GrantFiled: May 28, 2010Date of Patent: April 17, 2012Assignee: Universidad de GuanajuatoInventors: Jorge Ojeda Castaneda, Eduardo Aguilera Gomez, Hector Plascencia Mora, Miguel Torres Cisneros, Elias Rigoberto Ledesma Orozco, Alejandro Leon Martinez, Jose Sergio Pacheco Santamaria, Juan Gerardo Martinez Castro, Roberto Carlos Salas Segoviano
