Bodkin Design and Engineering (Newton, MA, USA) has been awarded a contract from the US Air Force to develop a high spatial resolution hyperspectral sensor operating in the longwave infrared (LWIR) spectral band.
A prototype system will be demonstrated as part of the Air Force Research Laboratory's efforts to improve target acquisition and threat assessment to protect both civilian and military assets.
Hyperspectral imaging combines a spatial image with spectral analysis to build up a three-dimensional data-cube (two dimensions of the data-cube are spatial and the third dimension is wavelength). There are several methods currently available for acquiring hyperspectral images, but they are limited in their ability to satisfy the military’s need for speed, accuracy, and data rate.
The company says that the system will capture spectral and spatial information with unprecedented data-cube size and speed. This will improve standoff target detection, materials identification, and the quantification of atmospheric constituents and effluents.
The nine month-long project has been funded under the Small Business Innovation Research (SBIR) program.
