Performance Testing of iX Cameras i-SPEED 727 High-Speed Camera
by Julien Manin
This work evaluated the iX Cameras i-SPEED 727, a commercial CMOS-based continuous recording high-speed camera. Various parameters of importance in the scheme of accurate time-resolved measurements and photonic quantification have been measured under controlled conditions on the bench, using state-of-the-art instrumentation. We will detail the procedures and results of the tests laid out to measure sensor sensitivity, linearity, signal-to-noise ratio and image lag. We also looked into the electronic shutter performance and accuracy, as exposure time is of particular interest to high-speed imaging. The results of the tests show that this camera matches or exceeds the performance of competing units in most aspects, but that, as is the case for other high-speed camera systems, corrections are necessary to make full use of the image data from a quantitative perspective.
The author would like to acknowledge Todd Rumbaugh of Hadland Imaging for the helpful discussions and for allowing us to borrow the camera for testing. This study was performed at the Combustion Research Facility.
