With this patented technology, AOA can now produce CCD camera systems with a depth of field more than ten times that of equivalent conventional camera systems. A unique optical design also keeps a constant magnification throughout that depth of field. These camera systems achieve their large depth of field with no moving focus element. Instead, a Wavefront Coded optical element prior to the CCD array optically encodes the captured image.
Subsequent hardware decodes the image in real time.
The technology works equally well on line scan or area scan camera systems and has a wide variety of applications in machine vision and electronic imaging. Parcels come in all different shapes and sizes, and now we can read labels and bar codes on curved and slanted surfaces. AOA develops and manufacturers a variety of machine vision and other electro-optic systems. Historically, most manufacturers and converters of materials produced in a continuous process, or web, have had trouble justifying the cost of a vision system. The low cost and high performance of the Advisor LT system reverses that trend.
