Jul 29, 2020 CyberOptics® Corporation (NASDAQ: CYBE) 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.
