These sensors are classified into different types based on the necessities of an exact application which includes ccd charge coupled devices cmos complementary metal oxide semiconductor psd positive sensitive detectors and photoelectric sensors.
Laser based sensors.
For robots being able to understand or navigate their environment is often critical to functioning properly.
Devices are available with either class 1 or class 2 lasers.
North america europe asia pacific apac rest of the world row recent developments.
Laser sensors are used for detecting presence based on position or light intensity.
Qcl sensors use mid infrared semiconductor laser sources either intraband quantum cascade lasers or interband cascade lasers to enable high precision high accuracy and selective detection of trace gases such as greenhouse gases and chemical agents with application to a variety of commercial industrial defense and environmental problems.
Equipped with intelligent interfaces and cables that are qualified for use with drag chains and robots these laser sensors can be applied in almost any measurement task in industrial automation.
Based on region the laser sensor market has been segmented as follows.
Laser diode sensors combine the alignment advantages of a visible sensing beam with the increased sensing range of a laser.
More than 85 laser sensors with measuring ranges from 2 1000mm cover a large number of applications across many different industries.
Types of laser sensor.
Laser based sensors from the technology data exchange linked to trusted tde listed vendors.
They are designed as through beam sensors retro reflective sensors or diffuse reflection sensors.
Laser sensors are used where small objects or precise positions are to be detected.
Benefits include long range a visible beam spot and precise detection.
Laser light consists of light waves of the same wave length with a fixed phase ratio coherence.
