US Patent:

20210055454, Feb 25, 2021

Filed:

Aug 20, 2020

Appl. No.:

16/997994

Inventors:

- Crane IN, US
Benjamin R. Conley - Bloomington IN, US

Assignee:

The United States of America, as represented by the Secretary of the Navy - Arlington VA

International Classification:

G02B 1/00
G01J 5/20
G01J 5/08

Abstract:

The present invention relates to a metamaterial focal plane array for broad spectrum imaging. Electromagnetic energy in the form of light is absorbed in or on a metamaterial absorber and a subsequent hot carriers are collected either in a semiconductor space charge region (e.g. P-N junction), or in some other modern collection scheme. Following the accumulation of photogenerated charge (electrons or holes), the signal is then converted to a digital signal using conventional or slightly modified ROIC modules.

International Classification:

G02B 23/12
G02B 13/16
H04N 5/33
H01L 31/103
H03F 3/08

Abstract:

Systems are provided including night vision goggles and up-conversion circuits for converting short wave infrared (SWIR) light into near infrared (NIR) light or other visible light in low-light environments. An array of electrically coupled photodiodes, amplifiers, and NIR light emitters generate and amplify a current in response to SWIR, powering the light emitters to generate NIR light. The NIR can then be directed into a photomultiplier tube to amplify the light and allow an operator to see in low-light environments.

International Classification:

H01J 40/06
H01J 40/16
H04N 5/33

Abstract:

Exemplary metamaterial photocathodes enable detection of light from visible through long wave infrared wavelengths. Metamaterial stacks, comprising gold, silicon, and cesium-oxide, coupled to a semiconductor allow hot electrons to efficiently enter a vacuum. The hot electrons are multiplied in a multichannel plate and directly through another vacuum towards a phosphorus screen.
