Time-of-flight systems are technologies that measure the time it takes for a signal, often light or sound, to travel to an object and back to the sensor. This measurement allows for precise determination of distances and is widely used in 3D reconstruction and industrial inspection. By capturing the time delay, these systems can create detailed spatial representations and detect flaws in manufacturing processes.

Review Questions
How do time-of-flight systems contribute to improving the accuracy of 3D reconstruction?
Time-of-flight systems enhance the accuracy of 3D reconstruction by providing precise distance measurements through the timing of signal reflections. When a light or sound pulse is emitted, the system calculates how long it takes for the signal to return after bouncing off surfaces. This data helps create accurate depth maps, allowing for detailed spatial models that represent real-world objects more faithfully.
Discuss the advantages of using time-of-flight systems in industrial inspection compared to traditional methods.
Time-of-flight systems offer several advantages over traditional inspection methods in industrial settings. They provide faster measurements with high precision, enabling real-time quality control on production lines. This speed allows manufacturers to detect defects quickly, reducing downtime and improving overall efficiency. Additionally, time-of-flight technology can easily integrate into automated systems, streamlining processes further.
