Laser sensor working

Definition and explanation of how LTI laser measurement products work to measure distance and other measurements using laser pulse technology. A laser sensor operates based upon the triangulation distance measurement principle. LAP laser sensors for measuring of dimensions.

Distance sensors type Mwith intuitive operation . The laser spot which is clearly visible even in daylight makes the alignment of the system easier.

Clearly visible red light for easy adjustment to the object.

Application sensors for special application areas.

System components for fine adjustment. As the figures above show, a laser beam emitted from the semiconductor laser is applied to the target. The light reflected from the target is collected by the receiver lens and focused on the light-receiving element.

When the distance to the target changes, the angle of the reflected light passing through the receiver lens . Theory of Operation : Optical Triangulation Graphic Advanced laser sensors operate based on the principle of optical triangulation, which incorporates the linear imager, identifying where the target is in front of the sensor to achieve an accurate, stable measurement. Due to high measuring rate, laser sensors from Micro-Epsilon offer high measurement accuracy and provide reliable even in continuous industrial operation. Therefore, set up and configuration of the sensors is convenient and can be stored and . Position based sensors are unaffected by color changes, surface variations or difficult angles.

This page explains how these sensors work. As shown in Fig a thermopile laser sensor consists of several thermocouples connected in series with one junction type (hot junction at temperature T1) being exposed to an . VDM1Series laser sensors for distance measurement applications provides high measurement, spee and accuracy at distances of up to 3meters. The Microtrak features state-of-the-art CMOS - CCD laser triangulation technology which is ideal for solving tough in-process, production and quality control sensing applications. The large variety of laser triangulation sensors provide operating distances to 300mm, measurement ranges to 200mm and . The laser light is focused through the emitting lens and projected on an object. General positioning is the most common application for laser sensors.

Their fast, highly linear response makes them ideal for both static and active feedback positioning applications. Large operating distance and measurement range provides the flexibility for process and quality control monitoring. This laser beam is reflected from the surface and falls on the detector through the lens.
