Abstract
Systems and Processes Engineering Corporation (SPEC) proposes to develop a straightforward methodology for the setup and operation of a rotating beam laser vibrometer to map and measure the vibrations of a rotating naval propeller in water. SPEC will develop a measurement system which integrates a laser vibrometer, a SPEC developed image derotator system, control software and straightforward alignment methodology. The compact image derotator system will incorporate remotely controlled piezoelectric alignment elements and integrated computer control for rotation and phase control. This component will provide a stationary image of the rotating object and probe beam and will provide visual feedback for the alignment of the probe beam with the rotational axis of the propeller. Various system configurations will be considered and the relative merits evaluated. The final delivered system will be a rotating beam laser vibrometer system with associated documentation for setup and operation
