High-performance, event-driven, low-cost, and SWaP imaging sensor for hostile fire detection, homeland protection, and border security
2012
The advanced imagers team at JHU APL and ECE has been advocating and developing a new class of sensor systems
that address key system level performance bottlenecks but are sufficiently flexible to allow optimization of associated
cost and size, weight, and power (SWaP) for different applications and missions. A primary component of this approach
is the innovative system-on-chip architecture: Flexible Readout and Integration Sensors (FRIS). This paper reports on
the development and testing of a prototype based on the FRIS concept. It will include the architecture, a summary of test
results to date relevant to the hostile fire detection challenge. For this application, this prototype demonstrates the
potential for this concept to yield the smallest SWaP and lowest cost imaging solution with a low false alarm rate. In
addition, a specific solution based on the visible band is proposed. Similar performance and SWaP gains are expected for
other wavebands such as SWIR, MWIR, and LWIR and/or other applications like persistent surveillance for critical
infrastructure and border control in addition to unattended sensors.
