THE OMETRON V9100, PART OF THE VPI (VIBRATION PATTERN IMAGER) SERIES, IS A NON-CONTACT VIBRATION MEASUREMENT SYSTEM UTILIZING LASER DOPPLER VIBROMETRY (LDV) TECHNOLOGY. THIS PRECISION INSTRUMENT IS DESIGNED FOR THE FULL-FIELD IMAGING OF STRUCTURAL VIBRATIONS WITHOUT MASS LOADING OR PHYSICAL CONTACT, MAKING IT SUITABLE FOR DELICATE OR HIGH-FREQUENCY APPLICATIONS. THE SYSTEM TYPICALLY INCLUDES A SCANNING LASER HEAD EQUIPPED WITH A HELIUM-NEON (HE-NE) LASER SOURCE AND INTEGRATED INTERFEROMETRIC OPTICS TO DETECT THE DOPPLER SHIFT OF REFLECTED LIGHT, WHICH IS PROPORTIONAL TO THE SURFACE VELOCITY OF THE TARGET. SUPPORTING A WIDE FREQUENCY RANGE OFTEN EXTENDING FROM NEAR-DC TO 25 KHZ OR HIGHER, THE VPI SENSOR PROVIDES HIGH SPATIAL RESOLUTION, CAPABLE OF RESOLVING MEASUREMENT POINTS WITH DIAMETERS AS SMALL AS 1 MM AT A 10 M WORKING DISTANCE. THE CONTROL CONSOLE PROCESSES THE OPTICAL SIGNALS INTO ANALOG VELOCITY OUTPUTS, TYPICALLY FEATURING A SENSITIVITY OF 10 MV/MMS-1 OR 100 MV/MMS-1 DEPENDING ON THE SPECIFIC CONFIGURATION. THE SYSTEM IS DESIGNED FOR HIGH ACCURACY, OFTEN BETTER THAN 1% AT THE ANALOG OUTPUT, AND INCLUDES FEATURES FOR MAPPING COMPLEX VIBRATION PATTERNS ACROSS SURFACES SUCH AS AUTOMOTIVE COMPONENTS OR LABORATORY SPECIMENS. CONNECTIVITY IS USUALLY FACILITATED THROUGH BNC SOCKETS FOR SIGNAL OUTPUT AND DEDICATED CABLES FOR HEAD-TO-CONSOLE COMMUNICATION. THE V9100 SERIES LEGACY IS CURRENTLY SUPPORTED AND INTEGRATED INTO THE BROADER TECHNOLOGY PORTFOLIO OF THE POLYTEC GROUP.
