- A Novel Microcontroller-Based Imaging System Utilizing a CMOS Image Sensor Array – Dr. Ralph Shiell, Trent University
Technology Overview:
Researchers at Trent have developed a compact, low power, flexible imaging system based on low-cost, widely available components with proven reliability. An active-pixel image sensor can be configured to tailor the temporal, spatial and optical resolution to the requirements of the user. Programmable microcontrollers permit sophisticated control and customization for any application.
Benefits:
– Compact and lightweight
– Low power consumption
– Sensitive to the entire visible spectrum and beyond, to near-IR; 5.4 fW/pixel sensitivity at 670 nm
– User adjustable sensitivity and resolution
– User configurable output protocol
– Unlimited flexibility of programmable microcontrollers
Fields of Use:
Imaging systems are widely used in industrial process control and optical measurement systems. However, flexible PC software-based systems using a frame-grabber with a CCD provide sophisticated control at high cost and with a large footprint. Meanwhile, self-contained, compact camera units lack the necessary controls for user customization and automation.
This device has applications in many sectors that require imaging, including precision machining, quality control, spectroscopic measurements and the characterization of the frequency components within light sources.
