Imaging Device

Abstract

A device for capturing images where the incident light passes through a modulator that adjusts to provide a selected image. Imagewise light is received in a sensor which is in communication with a processor that implements an optimization algorithm. The processor is in communication with the modulator and controls functioning of the modulator to optimize and to obtain the selected image.

1 . A device comprising:
 (a) an optional electromagnetic energy source; and   (b) a sensor for capturing imagewise electromagnetic energy from an object, wherein said imagewise electromagnetic energy is received through a:
 (i) spatial energy modulator in communication with 
 (ii) a controller comprising a parallel stochastic perturbation gradient descent or a simultaneous perturbation stochastic approximation optimization algorithm. 
   
     
     
         2 . The device of  claim 1 , wherein said spatial energy modulator is a pixelized liquid crystal device, a micromechanical mirror array, a piston mirror, a tip-tilt mirror or a deformable mirror. 
     
     
         3 . The device of  claim 1 , wherein said sensor is a CCD camera, CMOS camera or a very large scale integration imaging device. 
     
     
         4 . The device of  claim 1 , wherein said controller comprises a parallel controller. 
     
     
         5 . The device of  claim 1 , further comprising an integral device for executing said algorithm computations. 
     
     
         6 . The device of  claim 1 , wherein said energy source is a variable frequency source.
