The VL53L0X integrates a leading-edge SPAD array (Single Photon Avalanche Diodes) and embeds ST’s second generation Flight SenseTM patented technology. The Time-of-Flight principle (ToF) is a method for measuring the distance between a sensor and an object, based on the time difference between the emission of a signal and its return to the sensor, after being reflected by an object. – Technology, Uses, Projects to find out more. The VL53L1X embeds ST’s third-generation FlightSense patented technology. Time-of-flight sensors measure this time and use it to determine the distance of the object reflecting the waves, which can be used to measure level if the time-of-flight sensor is located on top of a container and pointed down, at the contents. Time of flight is the measurement of the time taken by an object, particle or wave to travel a distance through a medium.

For most of the ToF cameras, their maximum operation range is about 5~7m, but this ToF camera can reach up to 10m. The applications follow: User detection for personal computers/laptops/tablets and IoT (energy saving), Obstacle detection with Robots (Robotics), White goods (hand detection in automatic faucets, soap dispensers, etc. By modulating the amplitude, it creates a light source of a sinusoidal form with a known frequency which allows a detector to be able to determine the phase shift of the reflected light and by using the formula: where c is the speed of light (c=3×108 m/s), λ is one wavelength (λ=15 m), and ƒ is the frequency, each point on the scene can be easily calculated by the sensor to find out the depth. Next, ToF can also use continuous waves to detect the phase shift of the reflected light to determine depth and distance. Figure 1 illustrates the basic TOF concept. The VL53L0X is widely applicable, catering to all your potential needs! In addition, you can select a different IR filter of 850nm and 940nm. The ToF Sensor enables better macro shots.

When the two times are subtracted, the “time of flight” of the light is obtained, and the speed of light is constant, so the distance can be easily calculated using the formula above. Today we will be going through 2 ways that ToF use travel-time to determine distance and depth which are: For example, it works by firstly illuminating the target with laser light and measuring the reflected light with a scanner where the distance of the object is deduced using the speed of light to calculate the distance traveled accurately. What benefits do they have? Unlike other proximity sensors that use simple IR (Infra-Red) technology, which only measure signal strength and can be affected by the object’s reflectivity, FlightSense™ sensors directly measure distance to the object based on the time for … Is it a camera that captures a plane flight? Time of flight sensors can be utilized in a range of applications.
