Textured fiber optic coupled image intensified camera

摘要

A fiber optic bundle couples light from an image intensifier (I2) to an image sensor. The fiber optic bundle includes multiple cores for directing the light from the I2 to the image sensor, and each core has an output surface shaped into a recessed concave surface for focusing the light toward the image sensor. A bond layer is interposed between the output surface of the core and the image sensor. The bond layer is shaped into multiple micro-lenses, each micro-lens configured to conform to the recessed concave surface of each respective core.

1. A camera comprising:
an image intensifier (I2), an image sensor, a fiber optic bundle comprised of multiple individual fibers for coupling the I2 and the image sensor, and an output surface of the fiber optic bundle configured to provide light as an output to the image sensor, each fiber having a concave shape at the output surface of the fiber optic bundle, wherein the output surface of the fiber optic bundle is shaped to reduce spreading of the output light provided as an input to the image sensor, a bond layer is sandwiched between the output surface of the fiber optic bundle and the input surface of the image sensor, and the bond layer is in direct contact with the output surface of the fiber optic bundle and the input surface of the image sensor, wherein a top portion of the bond layer is shaped into multiple micro-lenses, and the concave shape of each fiber is configured to conform to each micro-lens of the bond layer.
