Golf clubs come in a variety of different types. Drivers are designed to generate distance, wedges to lift the ball out of difficult situations, and putters to gently place the ball in the hole. Golf club manufacturers are constantly pushing the technology in all of their clubs to achieve an edge over their competition with new designs that need to be experimentally analyzed and verified. One critical feature of a golf club is how it responds when the club impacts the ball. This response will affect the movement of the ball and the feel in the hands of the golfer. Polytec’s Multipoint Vibrometer (MPV-800) is an instrument that captures dynamic response data simultaneously at up to 48 points using lasers. Vibration can be captured at 48 discrete locations in 1D mode, or up to 16 points for resolving the complete 3D motion. The MPV-800 will measure the response to a single transient event, such as a golf ball impacting the head of a golf club. Some clubs are more forgiving than others, so that exact point of impact can affect its response and a small deviation may change how that club responds; therefore, it is important to strike the club only once and to capture data simultaneously. In our example we measured on the shaft, but this measurement can also be performed easily on the club head. We tested a 9-iron and a putter with the MPV-800 system. ]]>

Anna's hummingbirds are a local hummingbird species in coastal central California living in the region year round. A few migratory species such as the Allen's hummingbird migrate through the region spending winter in Central America and summer further north. The birds are very territorial and will fight for the best food sources. A hummingbird feeder in the backyard is an unlimited source of easy food that is worth fighting for (so long as the human residents keep filling it). Fights can get aggressive between rival hummingbirds, but typically a sequence of chirps and sometimes a game of chase is all that is needed for one bird to flee and another to gain dominance over a territory. The PowerPoint link below with embedded videos shows the chirps in the frequency range of 6-10kHz that can often be heard while a bird approaches the food source. The Acoustic Camera provided by Polytec and GFAI is used to capture these chirps as the hummingbirds fly through the air and to the feeder. The Acoustic Camera was the first commercially viable system using beamforming to visually localize acoustic emissions. Brought to the market in 2001 as a pioneer technique, the Acoustic Camera has become a metaphor over the years for beamforming systems in general. The tool is now used in a variety of industries and has a growing customer base worldwide. ]]>

Learn how dynamic torsional motion found in rotating bodies can be measured using non-contact angular velocity and displacement sensors. Controlling torsional vibrations is critical to designing reliable vehicles, electric power generators and aircraft propulsion systems. Rotational vibration data, used in the early stages of product development, has enabled design and test engineers to reduce noise, vibration felt by the passenger/operator, and to substantially increase durability. Classic examples of products with dynamic torsional motion are: drive shafts, universal joints, CV joints, electric motors, combustion engines, turbines, pumps, gearboxes / transfer cases. Discover how vibrometers can be used to measure the vibration at fixed points and scanned to characterize the entire surface even when the structure is rotating. Our experts in the field of vibrometry will be on hand to answer any questions you have about your current and future measurement needs and requirements. ]]>

The system features a very high optical sensitivity, which means that it can also be used on surfaces at distances that would otherwise require surface treatment for vibrometry measurement. The webinar will share examples showing how the RSV-150 saves time and effort when monitoring the health of structures, including the measurement of resonant frequencies and deflections of bridges subjected to traffic loading.
