SYSTEM AND METHOD FOR OPTICAL THREE-DIMENSIONAL PARTICLE LOCALIZATION

Embodiments include methods that may be used to optically obtain the precise three-dimensional location of multiple objects from one or more two dimensional images. An optical point spread function having a transverse shape which varies with axial distance may be implemented to obtain depth information. The transverse variation in the PSF with depth may be produced using a cylindrical lens. The objects may be imaged by a focal plane array detector. One or more 2D images may be used to find the 3D location of the objects using sparse signal reconstruction methods.
