High-speed laser triangulation sensor checks for industrial quality.


This high-speed PSD-based laser triangulation sensor Optical Triangulation Sensors
Optical Triangulation Sensors are commonly used to provide door mounted safety detection on swinging automatic doors. In North America, these types of sensors are very common and manufactured in very high volumes.

 laser distance sensor tracks object displacement or running profile changes at analog outputs up to a 100 kHz response.

This highly accurate, fast measurement rate makes these sensors an ideal choice for measuring vibration, alignment, distance, thickness, positioning and similar applications, according to according to

 the company. Differential measurement by two sensors allows on-line thickness and profile measurements to be made at the same high rates without sacrificing production speed or quality. Other uses include on- and off-line quality control, positioning, oscillation Oscillation

Any effect that varies in a back-and-forth or reciprocating manner. Examples of oscillation include the variations of pressure in a sound wave and the fluctuations in a mathematical function whose value repeatedly alternates above and below some
 measurement, surface control and other specialized inspection applications.

Other technical specifications include an available measurement range from 10 to 45 mm, depending on the model selected. The sensor's small laser spot size from 0.20 to 0.250 mm is said to make the sensor ideal for measuring small targets. Color and texture variations in the measurement target area are automatically compensated for by the sensor's variable laser power control circuit.
