Abstract
A method for selecting an image is presented.
Claims21
A method for obtaining a selected image of an object:
- (a) applying electromagnetic energy to said object to provide reflected and/or transmitted energy according to interaction of said electromagnetic energy and said object;
- (b) determining an image quality metric in accordance with said reflected and/or transmitted energy without the need for a wave front sensor or wave front aberration reconstruction to provide a determined image quality metric;
- (c) applying a perturbation to said image quality metric to provide a perturbed image quality metric;
- and
- (d) determining whether a predetermined image quality is obtained in accordance with said perturbed image quality metric to obtain a select image of said object.
2 more elements
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.
