Diode lasers for Machine Vision
Laser diodes are based on the same principle as LEDs. Due to additional optical resonators they produce a narrowband coherent light.
How to choose the right illumination for your application
There are a number of considerations when determining which type of illumination is best for a particular job:
- Is it a monochrome or colour application?
- How fast is the object moving in front of the camera?
- What physical size (area) needs to be illuminated?
- What is the nature of the object - geometry, structure, reflectivity, colour?
- Which features are of particular interest?
- What does the service life of the light need to be?
- What are the mechanical constraints/environmental considerations?
- How these questions are answered will determine which light is best suited to an application. The trend in imaging and machine vision is clearly towards LED and laser illumination.
