Laser distance measurement principle

This is known as the time of flight principle , and the method is known either as “time of flight” or “pulse ” measurement. LAP laser sensors for measuring of dimensions. Our sensors calculate the centre of gravity to define the measurement . A laser sensor operates based upon the triangulation distance measurement principle.

A laser distance meter can measure distances of up to 30m with an accuracy of É3mm.

This measuring principle , which is also used by laser devices, is known as the “ running time procedure”.

The speed of light is much higher than that of soun and the times involved are extremely short where distances are limited.

Clearly visible red light for easy adjustment to the object. Application sensors for special application areas. System components for fine adjustment. RS4and analogue interfaces from Page 198. Only low measuring rates with high current consumtion are possible the consequence.

Operating range (scanning distance) from 2mm to 7mm. It is possible to measure directly the time-of-flight of light. The principle is easy - the details are tricky.

Definition and explanation of how LTI laser measurement products work to measure distance and other measurements using laser pulse technology. The light reflected from the Measurement object is detected by the Sensor element. The measurement distance is derived from the propagation time of . The physical principles of wavelength-shift interferometric laser rangefinders”, J. PSD type sensors can determine the . We focus here on range measurement. Basically, two laser principles are common in land surveying: phase shift and pulse – also called time of flight – measurements. Multi-faceted and varied applications require laser distance sensors with versatile performance features.

Single point laser triangulation sensors for measuring distance and position with high spee accuracy and precision. Laser Displacement Sensors(1D). From this matrix image, the controller calculates the distance information (z-axis) and the position alongside the laser line (x-axis). The laser distance sensors are robust and deliver precise and reliable in harsh industrial applications. A range of various measuring methods such as phase comparison and the time-of-flight measuring principle are adopted to ensure this is the case: These methods are extremely reliable and are not susceptible to . From the position of the light spot on the Receiver element and . Triangulation Means distance measurement by angle calculation.

The unique sensor uses phase shift comparison measurement principles (of light) to accurately measure distances of meters. Longer ranges to 1meters are possible with the . A band-like laser beam is projected on the measurement object, and the reflection from the object is received by the CCD. A shape profile of the measurement object is formed based on the principle of triangular distance measurement.

General descriptiondi-soric laser distance sensors are used for precise measuring of distances down to the micrometer at diverse ranges. Due to the high reproducibility and .
