Technical Abstract (Limit 2000 characters, approximately 200 words):

Recording spatial and spectral content has been the traditional domain of hyperspectral cameras. They produce very large datasets that require significant storage, transmission and processing capabilities. Despite the great usefulness of this information, they are captured in a very inefficient way; in many important problems, only a tiny subspace of the signal is necessary to produce the corresponding results. That is the case of classification or target detection problems. Using hyperspectral data with state-of-the-art machine learning algorithms (such as deep neural networks) has been a considerable challenge due to the sheer data sizes, immense hardware requirements and long training cycles.

Our company has developed a technology that overcomes these hurdles. Our system captures spatio-spectral content in a compact, information-rich, monochrome image, termed diffractogram.  They can be used directly for inferencing, i.e., target detection and classification. This is achieved via optimally designed nanofabricated, diffractive-filter arrays (DFA) integrated into an existing sensors (FPAs).

Compared to traditional approaches, we have identified strengths that can be exploited for a class of applications:

• Applicable for any spectral range (UV, Vis, NIR, SWIR, etc).
• Adaptable to existing sensors (virtually any FPA can be used)
• Small signals with a high density of information (efficient storage and transmission)
• Produced by optical compression (signals be used directly, no need for any decompression)
• Snapshot capture (no line scanning; well suited for moving targets)
• No moving parts (physically robust)
• Efficient at detecting temporal changes
• High transparency (no filters imply more light can be used)
• Spectral continuity (recorded signal is not spectrally discretized)
• Small size and weight (single optical path and no complex scanning components)
• Multi-purpose (single system produces data that can be used in many applications)

          

          

     

Potential NASA Applications (Limit 1500 characters, approximately 150 words):

Detecting lighthing optically from space typically focuses on the single spectral signature at 777.3nm. It came to our attention from conversations with NASA experts Dr. Patrick Gatlin and Dr. Mason Quick that our technology had great potential to improve on the current approach since it can observe other spectral bands simultaneously and efficiently, resulting in an improved detection rate. Moreover, the system can be used for other applications that use space hyperspectral data such as vegetation monitoring, detection of algal blooms, etc.

          

          

     

Potential Non-NASA Applications (Limit 1500 characters, approximately 150 words):

Despite their usefulness and applicability in virtually every sector, hyperspectral sensors have not attained a wider adoption primarily due to two obstacles: 1) a very high price tag and 2) onerous data requirements. We offer significant reductions (at least 10x) in both, besides other advantages. We are developing a product that aims to satisfy the needs of that untapped market.
