What You'll Learn
Trackers use cameras and sensors to create a 3D space
Golf trackers have revolutionised the way the game is watched and played. They employ a combination of cameras and sensors to create a 3D space, allowing for the precise tracking of golf balls. This technology has been integrated into television broadcasts, providing viewers with an enhanced experience and detailed analytics.
The process begins with strategically placed cameras that capture the golf ball's movement. These cameras employ a custom-built sensor, such as the CMOS sensor used by Protracer, or utilise Doppler radar technology, as seen in TrackMan and FlightScope systems. The sensors play a crucial role in creating a 3D space by mapping out the area and identifying objects within it. This enables the system to accurately track the ball's flight path and calculate various metrics.
The sensors detect light waves created by the golf ball, allowing the software to pinpoint its location and trajectory. This data is then processed to generate on-screen graphics, showcasing the ball's path and providing valuable insights such as distance, height, speed, apex, curve, and carry. The system can even differentiate between multiple balls and assign them to the correct bay or player.
Toptracer, a rebranded version of Protracer, is a prominent example of this technology. It has become the gold standard in golf tracking, with its advanced sensors and cameras providing unparalleled accuracy. Toptracer breaks down the range into invisible triangular grids, enabling precise ball tracking by calculating the angle at which the ball enters and exits each triangle. This level of detail ensures that players can review their shots with utmost precision.
The integration of golf trackers into television broadcasts has transformed the viewing experience for fans. No longer solely dependent on the cameraman to follow the ball, viewers can now witness the flight of the ball in real-time, visualised through graphics that enhance their understanding of each shot's brilliance. This technology has empowered fans to appreciate the game on a whole new level, marvelling at the incredible distances and analytics that accompany each golfer's performance.

Metal oxide semiconductors are key components
Golf ball-tracking technology has evolved to the point where viewers can see the ball's flight path and analyse its speed, apex, curve, and carry in real-time. This technology is now widely available to golfers, who can use it to improve their game. One such golf ball-tracking technology is Toptracer, which uses metal oxide semiconductors (MOS) as key components.
Metal oxide semiconductors are compounds that have oxygen molecules in their structure, allowing them to interact with volatile compounds. They are widely used in electronic noses for gas detection due to their high sensitivity, resistance to humidity, and ageing effects. The unique characteristics of MOS make them a diverse class of materials, with properties covering almost all aspects of materials science and physics in the fields of semiconducting, superconductivity, ferroelectricity, and magnetism.
MOS capacitors are formed by depositing a silicon-oxide dielectric layer and then a metal top electrode on the surface of a semiconductor region that forms the bottom electrode. Metal oxide semiconductors are valence compounds with a high degree of ionic bonding. Their conduction band minimum (CBM) and valence band maximum (VBM) consist primarily of the metal (M) ns and oxygen (O) 2p orbitals, respectively. The interaction between these orbitals results in a significant disparity in charge carrier transport. The smaller effective mass of electrons in metal oxides indicates better electron transport compared to hole transport.
Several families of metal oxides have been identified as promising p-type semiconductors, including nickel oxide (NiO) and Cu(I)-based oxides like Cu2O and CuMO2 (M = Al, Ga, or In). These metal oxides have electronic band structures that facilitate electron or hole transport. However, good n-type or p-type conductivity cannot be achieved intrinsically, as intrinsic point defects serve as donors or acceptors.

Trackers use Doppler radar to track the ball
Golf trackers use a variety of technologies to track the ball, one of which is Doppler radar technology. TrackMan, for example, is a golf tracking system that uses Doppler radar to monitor the launch of a golf ball. It was created in 2003 by golfers and brothers Klaus and Morten Eldrup-Jørgensen, and radar engineer Fredrik Tuxen. Tuxen had previously worked with tracking bullets and missiles using Doppler radar. TrackMan is set up behind the golfer and is roughly the size of a laptop.
TrackMan's radar technology is unmatched when it comes to measuring the full ball flight. It can capture and provide a wealth of quality data. Traditional optical-based golf launch monitors can only capture useful data for a fraction of a second, whereas TrackMan's Dual Radar technology captures data for the entire ball flight, typically lasting about six seconds. With a sample rate of 40,000 samples per second per receiver, TrackMan's data collection surpasses the capabilities of optical systems by a large margin.
TrackMan's measurements can be broken down into specific data points, including swing data, collision data, trajectory data, and bounce and roll data. This detailed understanding can help golfers and instructors improve performance on the golf course. For example, it can be used to pinpoint landing position with remarkable accuracy, with its 3D trajectory mapping in real time, combined with comprehensive impact and launch information.
TrackMan's radar technology also has other benefits. For instance, it is extremely reliable and precise, and it works in any weather conditions, day or night. With its waves being a million times longer than light waves, radar can accurately measure activities over vast distances.
