How to Select Lighting for Product Inspection and Control

LEARN MORE ABOUT THE STEPS TO MATCH THE DESIGN TO THE REQUIREMENTS

Dr. Norman Axelrod

March 3, 2014

To improve the reliability and sensitivity of an optical inspection system, the optical design of the sub-systems and components should be well-matched to both the inspection requirements and the optical properties of the product of interest.

Vision & Sensors - 3-D Imaging

Optically Enhancing Images

From Basic to 3-D: Inspection and control using optical spatial filtering and diffraction.

Dr. Norman Axelrod

May 7, 2013

Image processing is usually done in order to extract information of interest from a busy image or to enhance the image.

Photonics, Electro Optics or Optoelectronics?

Dr. Norman Axelrod

February 28, 2012

Our intention here is to suggest, for comprehensiveness, the use of all three of these words-photonics, electro optics, and optoelectronics-to any relevant computer searches for products, jobs, literature and more.

Auto-Compensated Optical Sensing for Online Applications

Dr. Norman Axelrod

September 23, 2011

Auto-compensated photosensing systems are used to increase reliability and sensitivity of on-line defect detection, positioning, and other optical and laser systems.

Vision & Sensors: LEDS: LEDs 101

Dr. Norman Axelrod

September 1, 2011

To see the increasing use of LEDs, just look around. Their growing popularity is driving efforts to improve performance, reduce costs and further expand applications.

3-D Imaging for On-Line Product and Process Control

Dr. Norman Axelrod

July 6, 2011

The selection of an appropriate 3-D technique depends on the feature(s) to be quantitatively determined.

Automated Vision and Sensing: Truth or Consequences

Dr. Norman Axelrod

June 9, 2011

The earlier the truth about actual performance requirements are identified, the earlier there will be preferred consequences: simplifications and a reliable system.

Quality Communication of Optical Information

Dr. Norman Axelrod

May 4, 2011

In this blog, we will briefly discuss the epochal paper that provided the basis for how quality communication can be obtained in the transmission of signals (including optical) in noisy channels in demanding situations where signal integrity can be critical to practical use.

Quality Test & Inspection: Smart Machine Vision Systems

Dr. Norman Axelrod

January 26, 2011

Machine vision systems with smart software can provide measurements more efficiently than ever before.

Image Processing Broken Down

Dr. Norman Axelrod

January 3, 2011

Determine when to apply digital vs. optical image processing techniques.

Discover how SPC's real-time data collection, monitoring and control capabilities provide the perfect foundation for AI/ML's predictive insights, enabling both immediate process optimization and long-term continuous improvement.

This webinar, featuring a live demonstration, will showcase the evolution of Hexagon’s direct scanning laser trackers: cutting-edge technology that now delivers traditional reflector-tracking accuracy to non-contact, large-part scanning.
