We will define and prototype four algorithms essential to efficient storage and extraction of information from Digital Array Scanned Interferometers (DASIs) to determine the feasibility of operating DASIs in "real-time." These algorithms, integral to DASIs, will ensure low cost, size, and weight for aircraft and spacecraft operations. "real-time" operation is a key aspect to research and commercialization. The four algorithms map into these broad categories:1. Loss-less spectral/spatial data compression.2. "Real-time" data preprocessing.3. Post processing algorithms that quickly extract and present relevant information.We intend for these algorithms to support "real-time" operations of DASI instruments, be implemented compactly and efficiently, and process without error. We intend to demonstrate how 2:1 loss-less data compression; data encoding at 200 Megabits/sec; and post-processing within minutes can be achieved.The algorithms will support the high throughput and high spectral fidelity and response typical of DASI instruments, where spectral resolutions of a few nanometers and spatial resolutions of high order have been achieved. Commercial Applications:Without high performance algorithms, essential for compressing DASI data, encoding in "real-time", and enhancing signal-to-noise, long collection integration times and a minimum of several hours and perhaps even days of laborious data processing is now required. Viable commercial applications (and efficient research) will only be realized once "real-time" data processing is achieved. Commercial applications include monitoring contaminants and bacteria found in our food; detecting and measuring contaminants in human blood; detecting algal blooms which deplete our fish supplies; and ensuring compliance with regulatory policy and environmental laws. To cite an example using "real-time" data processing with a DASI instrument, the canning industry would monitor bacteria content to ascertain the effectiveness of their sterilization cooking process and eliminate unnecessary retorting, thereby providing shorter production times, tastier products and lower prices to consumers.
