Abstract

A method for selecting an image is presented.

Claims

1. A device comprising:

(a) an electromagnetic energy source; and

(b) a sensor for capturing reflected and/or transmitted energy from an object exposed to said energy source, wherein said reflected and/or transmitted 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, a 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 the energy source is a variable frequency source.
