The CMHFVS sensor is a unique state-of-the-art computational imaging system with the capability of real-time adaptive configurability to address user’s needs in challenging multiple-threat and multiple-mission environment.
The CMHFVS sensor is adaptive configurable in real time and carries out multi-missions in one platform. “Adaptive Configurability” is such that the sensor hardware and software allows adaptation of sensing/perception parameters like spatial, temporal, spectral resolution, field of view and processing latency in real-time on-the-fly. It enables “Multi-Mission” via the adaptive configurability with the capability to conduct more than just one mission in a manner similar to the human visual system, i.e., detection-of-x, identification-of-y, tracking-of-z, over-watch, and situational awareness. It is a vital tool for instantaneous target detection & recognition relying on a few frames of direct HS CS measurements.
The offered sensor is implemented with both a single pixel detector path for high sensitivity and fast frame rate grayscale imaging; and a spectrometer path for HS imaging. Both paths share a common objective lens and programmable DMD aperture for 2-D spatial coding. The implemented software executes data acquisition, reconstruction for real-time coarse resolution video preview, and reconstruction for fine resolution.
The sensor enables:
- Flexible selection between MS and HS sensing modes;
- Fast sampling rate for target identification;
- Flexible fovea with arbitrary region of interest (ROI) number, size, location, and resolution in both spectral and spatial domains;
- Compact size, weight, and power consumption plus cost (SWaP-C).
The offered sensor can be used as a scientific research backbone platform for facilitating advanced Compressed Sensing, Machine Vision, Deep Learning research, and also a good education platform for college students to study in the field of artificial intelligence (AI).
The CMHFVS comes with a complete hardware package with the software for data acquisition, reconstruction and display.
