Lasersõelad

Lasersõelad, often translated as laser sieves or laser screens, are a type of sensor technology used to detect and measure the presence and properties of objects or particles in a specific area. They operate by emitting a laser beam and then analyzing the way this beam is interrupted, reflected, or scattered by an object or particle. This interaction allows the sensor to determine the size, shape, velocity, or presence of the target.

The fundamental principle involves a laser diode emitting a focused beam of light. This beam passes through a detection zone. When an object or particle enters this zone, it interrupts the laser beam. A photodetector, positioned to receive the laser light, registers this interruption. The degree of interruption, the duration, or changes in the reflected light can be processed to extract information about the detected item.

Lasersõelad find application in various industrial and scientific fields. They are commonly used in automated manufacturing for quality control, such as inspecting components or counting items on a production line. In logistics, they can be employed for dimensioning packages or detecting obstacles in conveyor systems. Their precision also makes them useful in scientific research for particle analysis or flow measurement. The specific configuration and processing algorithms determine the capabilities and accuracy of a particular lasersõelad system.
