FARSEER™
Proprietary noise reduction and phase correlation and correction processing allows for extremely high resolution imaging using a distributed array of relatively low-tech sensors
Optical Sensing Array
Opportunities and Challenges of Intensity Correlating Imaging:
-
Does not require the propagation of collected light beams to combiner units. Routing optics and beam combiners are eliminated.
-
Does not require nanometer level control of nor knowledge of the relative positions of the optical components.
-
SNR does not suffer from beam splitting and the throughput losses that plague amplitude interferometry.
-
ICI does not require diffraction limited optics, since the sole purpose of each telescope is to place photons onto a photo detector.
-
ICI is insensitive to atmospheric turbulence and therefore can be used by ground based, as well as space based facilities.
-
Estimating coherence magnitude from intensity cross correlations has low SNR -> Very long averaging times.*
-
Coherence phase must be reconstructed in order to compute the image. (very large dimension, highly nonlinear)*
*Recent advances in phase retrieval solve both problem
