OBJECTIVE: Development of an infrared imager with an ultrawide bandpass encompassing the Near Infrared (NIR) to the Mid-Wave Infrared (MWIR) spectrum: 0.7 micrometers to 5.5 micrometers.

 

DESCRIPTION: Broadband infrared imagers are required to characterize signatures of military targets, both cooperative and hostile.  The specific need is the characterization of missile plume and hardbody signatures in static and free flight tests.  This threat characterization supports the design and testing of missile warning and countermeasure systems.  The combination of a broadband imager with multiple filters allows registered imagery to be acquired in multiple bands, covering a broader spectral range than currently available hyperspectral imagers.  The multi-band ultra-broadband data would also be useful in temperature/emissivity determination of hypersonic thermal protection systems during ground tests in arc-heated facilities.  The infrared detector material InAsSb is an enabling technology to be considered.

 

PHASE I: The Phase 1 effort should develop and prove the feasibility of the proposed approach through an analysis of alternatives, identification of high-risk technical elements, and generation of a conceptual design matrix that lays out how achievable design parameters impact system requirements – e.g. frame rate achievable as a function of focal plane array size.  The system design should be sufficiently detailed to guide the Phase II work with a minimum of risk.    The Phase I effort will culminate in a conceptual design that optimally meets system requirements and a detailed plan for development of a prototype system during the Phase II effort.

 

PHASE II: The conceptual design will be matured into a detailed design.  Iterative prototypes will be developed to validate the fundamental approach.  The Phase II effort will culminate in the demonstration and delivery of a fully operational prototype imager along with a validated design for future larger scale production.

 

PHASE III DUAL USE APPLICATIONS: Phase III efforts would include a limited production of a number of imagers for inclusion in existing signature measurement systems, such as the Arnold Engineering Development Complex Field Measurement Team and the Center for Countermeasures Joint Standard Instrumentation Suite.  Broadband infrared imagers of this type would find wide military application for surveillance, night vision, and target detection, identification, and tracking.  As mentioned above, applications for non-contact temperature/emissivity measurements for hypersonic systems and other defense applications are also possible.   Commercial applications for security, surveillance, and non-contact imaging thermometry for manufacturing should also be pursued.  Infrared imagers are now a ubiquitous piece of laboratory hardware.  Advances in infrared imagery will find wide application supporting many disciplines.
