Description
The Air Force Research Laboratory (AFRL) is seeking a Polytec VibroFlex Connect Fiber Optic Laser Doppler Vibrometer System for the Structural Validation Branch at Wright-Patterson Air Force Base, Ohio. The system must meet specific requirements, including a laser wavelength of 1550 nm, a fiber optic lens extender or integrated fiber optic cable, and a minimum bandwidth of 50 kHz. The system will be used to capture high-temperature velocity measurements of structural components.
• The system must be capable of measuring a minimum velocity of 12.5 m/s.
• The system must have a baseline noise floor below 75 µm/s on any untreated surface.
• The system must be fully functional at a standoff distance of up to 100 meters from the test article to the sensor.
• The system must include a measurement software management system, Polytec MDE-Controller software, capable of managing and controlling each sensor’s settings.
• The system must provide an analog voltage output, with any range between 0 and 10 volts being sufficient.
• The system must include an option to display output in terms of displacement and acceleration.
