Area of Science:

• Electronics
• Computer Engineering
• Image Processing

Background:

• Reconfigurable detectors are crucial for edge computing and advanced imaging like foveation.
• Current systems lack dynamic control over sensing and readout modes, leading to inefficiencies.

Purpose of the Study:

• To present a novel camera system with simultaneous passive imaging and dynamic ranging capabilities.
• To enable adaptive-autonomous detectors with spatial and temporal control for enhanced data acquisition.

Main Methods:

• Developed a method for seamless switching of time frames and readout modes without data corruption.
• Implemented a data control and transmitter (DCT) for synchronized data transfer and serial off-chip transmission.
• Utilized a minimum unique data format to maximize data throughput and minimize dead time.

Main Results:

• Demonstrated seamless mode switching without requiring the data acquisition system (DAQ) to stop or resynchronize.
• Achieved maximized data throughput through an optimized data format.
• The DCT successfully operated at 1 GHz in a 65 nm LP CMOS process.

Conclusions:

• The presented method enables efficient and flexible data acquisition for reconfigurable detectors.
• This technology supports advanced imaging techniques and edge computing applications.
• The DCT provides optimized decision support and high-speed data transmission.
