Short focal length small aperture cameras are everywhere you look, proliferating in cell phones, web cams, personal recording devices, drone surveillance systems, and of course, automobiles. Heightened consumer expectations regarding high quality imaging performance and the use of many cameras in automotive safety systems have established a need for high performance test equipment for these devices that did not exist just a few years ago.
The Meridian® family of test equipment is our answer to this need. We first developed the Meridian Starfield product line in which high volume testing requirements are answered by illuminating multiple field points simultaneously and assessing imaging performance in just a single video frame. Then followed the introduction of our Focusing Target Projector (FTP) suite, in which apparent object distances of reference targets are set on demand. The newest member of this growing family is the Meridian FLEX—a highly configurable testing platform that not only answers the testing challenges that our customers face right now, but is also designed to address many they have yet to encounter.
The members of the Meridian family have this in common: they can generate fields of virtual objects in a compact space, obviating the need to place enormous test targets at a large distance. Wide field cameras need ever wider test targets, and there comes a point at which printed targets can no longer serve the need.
The I-SITE system is designed to provide measurements at multiple points in the signal processing chain for many types of camera systems. I-SITE can be expanded to accommodate multiple measurements and can be upgraded to incorporate additional modules as the user’s system requirements change. There are many options that may be employed; thus there is no single I-SITE setup. Sources, detectors, and intermediate optics may all be configured to your requirements, and several different analysis options are offered.
