Patent attributes
A system for type-2 ghost imaging of an object located in or obstructed by a turbulent air section includes a thermal light source, a beamsplitter configured to split light from the thermal light source into two optical paths of substantially equal length, a surface divided into two regions of equal area, a first region including the object and a second region that does not include the object, a narrowband spectral filter, and at least one detector having a predetermined spatial resolution and a predetermined temporal resolution. The object is located on one side of the turbulent air section and the at least one detector is located on another side of the turbulent air section. The at least one detector may be a large area picosecond photo-detector (LAPPD) having a spatial resolution of the order of millimeters and a temporal resolution of the order of 10 to 100 picoseconds.
