Laser Displacement Sensors vs. Conventional Displacement Sensors

	Laser Displacement Sensor	Conventional Displacement Sensor
Measurement Principle	Based on laser triangulation or interferometry, calculating displacement by emitting a laser beam and analyzing reflected light.	Potentiometer: Measures displacement via resistance changes. LVDT (Linear Variable Differential Transformer): Uses electromagnetic induction. Ultrasonic: Relies on sound wave reflection time. Eddy Current: Depends on electromagnetic field variations.
Measurement Method	Non-contact: No physical touch, avoiding wear or interference.	Contact (e.g., potentiometer, LVDT): Requires touching the object, risking wear. Non-contact (e.g., ultrasonic, eddy current): Limited precision or applicability.
Accuracy & Resolution	Accuracy up to micrometer (μm) or even nanometer (nm) level, with ultra-high resolution.	Potentiometer/LVDT: Typically millimeter-level. Ultrasonic/Eddy Current: Millimeter to sub-millimeter, prone to environmental interference.
Response Speed	kHz-level sampling rate, ideal for high-speed dynamic measurements (e.g., vibration analysis).	Potentiometer/LVDT: Slower (Hz-level). Eddy Current: Faster (kHz-level), but limited range.
Application Scenarios	- Precision manufacturing (semiconductors, electronics). - High-speed moving objects (e.g., production lines). - Fragile or high-temperature objects.	- Potentiometer: Low-cost, simple displacement monitoring. LVDT: Industrial mechanical positioning. Ultrasonic: Long-distance, non-precise measurements. Eddy Current: Short-range metal detection.
Environmental Adaptability	- Resistant to electromagnetic interference but sensitive to surface reflectivity (color, material). - Requires protection against strong light or dust (IP65/IP67 rated).	- Eddy Current: Only works on metals. Ultrasonic: Affected by temperature, humidity, and air pressure. LVDT: Resistant to oil but bulky.
Cost & Complexity	Higher cost, requires optical calibration, and more complex setup.	Lower cost (e.g., potentiometer), easy to install and maintain.
