Laser inspection involves the use of a specific type of photoelectric sensor that employs a highly focused beam of light to detect surface defects at a microscopic level, count parts as they move through production and scan codes or serial numbers as needed for a given application. While other vision inspection systems are also used to this extent, many industries prefer lasers which offer non destructive mechanical and structural evaluation for parts, equipment, repairs and products.

Aerospace, warehouse, pharmaceutical, automotive, food processing, communications, and retail industries among others rely heavily upon laser inspection services in conjunction with vision sensors and software. With such broad capabilities, it is important to consider the performance specifications of a given laser inspection system with regards for its intended use in the industrial or commercial sector.

Common concerns include sensing mode, detecting range, position measurement window, resolution, available memory and response time. Properly applied laser inspection technology allows for the partial or fully automated sequencing of in-process and in-line testing and surveillance of products and materials.

The word laser is actually an acronym for "light amplification of stimulated emission of radiation." While many different wavelengths and types of lasers are widely available they share common features. The light produced by a laser is a coherent, monochromatic and highly directional. Furthermore, these beams do not expand over long distances as does ordinary light. This is important as it allows the extreme accuracy required in laser inspection applications.

Accurate results are not, however, achieved by the use of lasers alone. Instead, the devices are used in conjunction with vision sensors, processors and vision software to provide manufacturers with the complete data set for an object, component or material. The function of these photoelectric emitters and receivers is relatively straightforward. A mirror is used to direct a focused beam of consistent wavelength towards the surface of the item to be examined.

The light is then reflected back in varying amounts and intensities which are measured by pre-programmed software which collects the data and translates it into a user friendly readout. Fully automated systems go a step further and use this data to engage machines or robotics to remove defective components or sort parts as needed. Some laser inspection applications require that every item be passed under the device, while others select samples at random. Although the latter leaves some room for error, it is sufficient in most settings and still provides more adequate coverage than visual inspections by the workforce.
