CyberOptics to Present Technical Paper at SPIE Optics + Photonics 2020 On-Line Conference


Reading time ( words)

CyberOptics® Corporation, a leading global developer and manufacturer of high-precision 3D sensing technology solutions, will present at the SPIE Optics and Photonics On-Line Conference on August 24 during the SPIE Optical Engineering and Applications Symposium’s verification and alignment session from 8:20 to 10:00am.

Dr. Matthew Jungwirth, Senior Optical Scientist at CyberOptics, and SPIE Senior Member will present the technical paper “Linearization of defocus for projector optical alignment in structured light illumination systems” at the SPIE Optics + Photonics conference. The paper outlines an advanced manufacturing alignment method that speeds up the process. Dr. Eric Rudd, Electronics Engineer at CyberOptics, is a co-author. 

High-quality imaging is typically dependent upon well-focused optical systems. CyberOptics presents a method that linearizes defocus to provide a clear zero-crossing along the optical axis for structured light illumination (SLI) systems. Here, sinusoidal fringes are projected onto a quad target, a diffuse target with different heights along the optical axis in separate quadrants. Shifting the focus alters the fringe contrasts on the quad target. Best focus is achieved when the contrast between the different heights is balanced.

The method was tested using a CyberOptics developed SLI system that utilizes advanced Multiple Reflection Suppression™ (MRS™) technology and compared to a published phase-shifted reconstruction technique. The non-linear defocus behavior was efficiently linearized using the quad target method as evidenced by linear regressions. Focal position estimates agreed well with the phase-shifted technique, thereby demonstrating viability of the method.

When I look at the landscape of U.S.-based PCB fabricators, the title of this article reminds me of a 1960s protest song. If you don’t remember the song or that era, you have some interesting research to do. As well, a Hank Williams Jr. song comes to mind, “All my rowdy friends have settled…” Seriously, I am pleased to see many of my old friends taking advantage of the present opportunities.

Initiatives like the IPC Connected Factory Exchange (CFX) and IPC-Hermes-9852 underpin efforts within the industry to develop standards and help create a smart factory. These M2M communication standards, guided in part by Industry 4.0, are altering the manufacturing process by improving metrics such as first pass yield and throughput by applying autonomous process adjustments.
