Optical Distance Sensors Explained: What They Are, How They Work, and Why They Matter

광학 거리 센서

광학 거리 센서란 무엇이며 어떻게 작동하나요?

광학 distance sensors are 비접촉식 측정 devices that use light—often laser or LED—to determine the distance between the sensor and a target surface. These sensors are widely used in industrial automation, robotics, level monitoring, and smart devices due to their high precision and versatility.

How Optical Distance Sensors Work

광학 거리 센서

Optical sensors operate by emitting a light beam and detecting the reflection from a surface. The most common working principles include:
1. Reflective Sensing
In simple reflective sensors, a beam of light is emitted and bounced back from the target. The sensor measures the time or intensity of the reflected light to estimate distance. This method is cost-effective and widely used in consumer electronics.
2. Triangulation Method
Triangulation-based optical distance sensors use geometry to determine the position of the reflected light on a receiver (such as a CMOS sensor). As the object gets closer or farther, the angle of the reflected light changes, enabling precise distance calculation—ideal for short to mid-range measurements.
3. 비행 시간 (ToF)
Time-of-flight sensors emit a laser pulse and measure the time it takes to reflect off the target and return. This method offers accurate, long-range measurement capabilities and is less sensitive to surface color or reflectivity.
💡 Laser-based optical distance sensors are a leading type of ToF device, offering high-precision, eye-safe operation suitable for industrial, agricultural, and UAV applications.
