Summary

The Department of Defense (DOD) is seeking proposals for a spectroradiometric suite as part of their SBIR 24.1 BAA solicitation. The objective is to develop a single system that can perform automated spectroradiometric measurements across the ultraviolet, visible, and infrared spectrum, ranging from 200nm to 14500nm. This system will be used to characterize EO/IR imagers and perform filter and optical window transmittance measurements. The spectroradiometer system should have the ability to select spectral resolution and bandpasses within the operating spectrum. The system should cover the desired wavelength range, have sufficient spectral resolution, detect low-sensitivity spectral signals, demonstrate stability over time, integrate with other radiometric systems, provide data in a suitable format, have a user-friendly interface, and be designed for operation in a laboratory environment. The project will be conducted in three phases: Phase I will focus on feasibility, Phase II will develop a working prototype, and Phase III will involve commercialization and customization. The complete system should be at Technology Readiness Level (TRL) 6 or greater for Phase III. The solicitation is open until February 21, 2024.

Description

OUSD (R&E) CRITICAL TECHNOLOGY AREA(S): Integrated Sensing and Cyber

 

The technology within this topic is restricted under the International Traffic in Arms Regulation (ITAR), 22 CFR Parts 120-130, which controls the export and import of defense-related material and services, including export of sensitive technical data, or the Export Administration Regulation (EAR), 15 CFR Parts 730-774, which controls dual use items. Offerors must disclose any proposed use of foreign nationals (FNs), their country(ies) of origin, the type of visa or work permit possessed, and the statement of work (SOW) tasks intended for accomplishment by the FN(s) in accordance with the Announcement. Offerors are advised foreign nationals proposed to perform on this topic may be restricted due to the technical data under US Export Control Laws.

 

OBJECTIVE: The objective is to have an single system that can perform automated spectroradiometric measurements across the ultra-violet, visible and infrared spectrum, 200nm to 14500nm. System will be used to characterize EO/IR imagers (spectral responses) and perform filter and optical window transmittance measurements. System will have the ability for the user to select spectral resolution and bandpasses within operating spectrum.

 

DESCRIPTION: Design and fabricate a spectroradiometer system that enables the system to make automated measurements from 200nm to 14500nm. System will produce spectral responses for radiometers and imaging sensors and transmittance curves for filters and optical windows.  Meeting the requirements below ensures that the spectroradiometer system is capable of accurately characterizing the spectral responses and transmittance of optical systems, allowing for various scientific, industrial, and research applications.

 

Spectral Range: It should cover the desired wavelength range relevant to the sensor’s application, this should include ultraviolet, visible, and infrared regions. Threshold wavelength range – 200nm to 14500nm

 

Spectral resolution: The system must have sufficient spectral resolution to distinguish between different wavelengths accurately. Higher resolution allows for more precise analysis of spectral features.

Sensitivity: The spectroradiometer should be able detect and measure low-sensitivity spectral signals, to ensure accurate and reliable data collection.

 

Calibration: Regular calibration is crucial to maintain accuracy and traceability of the measurements.

Stability: The system should demonstrate stability over time to ensure consistent and repeatable measurements.

 

Integration with other radiometric systems: The spectroradiometer must be designed to integrate seamlessly with other COTS systems, threshold - GigE Vision Standard interface.

 

Data Output: The system should provide data in a format suitable for analysis, often in the form of spectral radiance, spectral irradiance, normalized spectral , or transmittance.

User Interface: A user-friendly interface is essential for easy operation, data visualization, and data processing.

 

Environmental Considerations: The system needs to be designed to operate in a laboratory environment.

Cost and Size: Depending on the application and portability requirements, the spectroradiometer should be affordable and available in a suitable size.

 

 

PHASE I: In Phase l, the vendor will determine the ability of creating a single automated system that can make sprectroradiometric measurements from 200nm to 14500nm.  Feasability to combine multiple reference detectors in one system to span overlapping regions of UV, visible and IR. And the ability to provide a source with high spectral resolution across the 200nm to 14500nm region.

 

PHASE II: Phase II will demonstrat a working protype spectroradiometer that operates across the 200nm to 14500nm wavelength range. The system will be able to provide spectral responses for any given sub-band within the threshold wavelength range. Additionally, the system will be capable of measuring the transmittance of filters and optical windows within the threshold wavelength range.

 

PHASE III DUAL USE APPLICATIONS: For entrance into Phase lll, the complete system shall be TRL 6 or greater. In Phase III the vendor will be capable of producing a fully working automated system with accessories that allow customers to tailor the system to interface with other COTS or custom sensors outside of the original design parameters. Input from other AF agencies and services will be provided to further broaden commercialization requirements.
