What is ToF?
Time-of-Flight (ทีโอเอฟ) is a distance measurement technology that calculates how long it takes for a light signal—usually from an infrared or laser emitter—to travel to a target and reflect back. This round-trip time is then converted into distance with high accuracy. ToF sensors are compact, energy-efficient, and well-suited for a wide range of applications such as occupancy detection, tank level monitoring, object avoidance, และ even 3D scanning.
Key Advantages of ToF Sensor
1.มีความแม่นยำสูง
ToF sensors can achieve millimeter-level precision, making them well-suited for applications requiring exact measurements, such as detecting inventory gaps, desk presence, or material levels.
2.Fast Response Time
With response speeds in the millisecond range, ToF enables real-time detection and dynamic interaction, even for fast-moving objects or environments requiring instant feedback.
3.Non-Contact Measurement
ToF offers fully contactless operation—no need for physical interaction with the object. This makes it ideal for hygienic, sealed, or hard-to-reach environments.
4.Reliable in All Lighting Conditions
ToF sensors operate effectively in both bright and dark environments, as their performance is based on light travel time rather than ambient illumination—unlike many vision-based systems.
ToF vs. Other Distance Sensing Technologies
| เทคโนโลยี | หลักการทำงาน | ความแม่นยำ | Anti-Interference | ค่าใช้จ่าย | คุณสมบัติ |
|---|---|---|---|---|---|
| ทีโอเอฟ | Measures light’s time of flight | สูง | ปานกลาง | Low–Medium | เร็ว, กะทัดรัด, non-contact sensing |
| Ultrasound | Measures time of sound reflection | ปานกลาง | Prone to wind/noise | ต่ำ | Inexpensive, best for large or coarse object detection |
| LiDAR | Laser scan + ToF or triangulation | Very High | สูง | สูง | Extremely precise but costly and complex |
| Structured Light / วิสัยทัศน์ | Depth from image deformation | สูง | Affected by lighting | สูง | Common in 3D scanning, facial recognition, needs clear view |
Why Choose ToF?
ToF strikes the balance between accuracy, ความเร็ว, cost-efficiency, and adaptability. Unlike cameras or ultrasonic sensors, it works reliably across various lighting and spatial environments without compromising privacy or requiring complex processing. Whether you’re designing a smart office, monitoring warehouse inventory, or enabling tank-level sensing, ToF is a smart, scalable option for precise spatial awareness.
