Imaging System

A device for generating an image of points in a field of view, comprising:

• a plurality of directional signal sensors, a plurality of logarithmic converters, each of the plurality of directional signal sensors being connected to a corresponding one of the plurality of logarithmic converters;
• a plurality of transient detectors, each of the plurality of logarithmic converters being connected to a corresponding one of the transient detectors;
• a plurality of comparators, each comparator being connected to compare a signal from a corresponding one of the plurality of transient detectors and a signal indicative of a background flux transient to provide a difference signal corresponding to the respective one of the directional signal sensors;
• and a plurality of coincidence detectors, each coincidence detector being associated with a group of the plurality of directional signal sensors, each coincidence detector being connected to receive the difference signals corresponding to the associated group of directional signal sensors.

A coincidence detector, comprising:

• a first line comprising a plurality of first, second, third and fifth materials;
• and a second line comprising a plurality of first, second, fourth and sixth materials and oriented such that a portion of the second line is proximate a portion of the first line;
• wherein:
• when excited, the third material radiates a third-type signal that excites the third material;
• when excited, the fourth material radiates a fourth-type signal that excites the fourth material;
• when excited, the fifth material radiates a fifth-type signal that excites the fifth material;
• when excited, the sixth material radiates a sixth-type signal that excites the sixth material;
• when excited by a coincidence of the third-type and fourth-type signals, the first material radiates a visible light in a first color;
• when excited by a coincidence of the fifth-type and sixth-type signals, the second material radiates a visible light in a second color;
• whereby, if the first line is excited by the third-type signal and the second line is coincidentally excited by the fourth-type signal, or the first line is excited by the fifth-type signal and the second line is coincidentally excited by the sixth-type signal, the coincidence detector produces visible light of the first or second color, respectively, in a region where the first line is proximate the second line.

A coincidence detector, comprising:

• a first line comprising a plurality of first and second materials;
• and a second line comprising a plurality of first and third materials and oriented such that a portion of the second line is proximate a portion of the first line;
• wherein:
• when excited, the second material radiates a second-type signal that excites the second material;
• when excited, the third material radiates a third-type signal that excites the third material;
• when excited by a coincidence of the second-type and third-type signals, the first material radiates a visible light;
• whereby, if the first line is excited by the second-type signal and the second line is coincidentally excited by the third-type signal, the coincidence detector produces visible light in a region where the first line is proximate the second line.
