Prosilica GigE Vision Cameras Tested for New NASA Recording System
Developed by image acquisition and processing specialists Alacron, the new system, currently in development, will record the vehicle’s health and status during liftoff and free fall-back to Earth and must be able to endure vibration and shock at high G forces as well as record multiple hundreds of megabytes per second over an extended period. In addition, the system must store and retain data despite power loss, provide camera control and have the ability to download data afterwards via common data interfaces (including GigE) to computer systems running any operating system without the installation of special software. The system, named Fast-Vault, is a combination of two on-board systems into a 6U VME-form-factor board; a high-speed, 320-Gbyte flash memory system; and an I/O subsystem that provides interfaces to multiple cameras, along with analog and digital inputs.
Prosilica cameras were selected for this system because of their industrial ruggedness and high level of performance in the most demanding applications.
The GC650, GC660 and GC1380H are noted for ultra-compact size which facilitates integration in systems where space is limited, fast frame rates (up to120 fps at full resolution and even faster using area of interest readout) and excellent image quality.
In addition, Prosilica’s GigE cameras are capable of streaming data at a sustained rate of 125 megabytes per second over their gigabit Ethernet interface - 25% faster than our nearest competitor.
