Optical Advancements Enable High-Precision 3D Imaging

Facebook Twitter LinkedIn Email

Advancements in engineered point spread function (E-PSF) technology, in the form of optical phase plates, will enable manufacturers to meet rising demands for ultraprecise object imaging.

LESLIE KIMERLING, WARREN COLOMB, and ANURAG AGRAWAL, DOUBLE HELIX OPTICS

As robotics and automation change the face of manufacturing, demands on industrial inspection have increased. Advancements in engineered point spread function (E-PSF) technology are now allowing manufacturers to incorporate high-resolution 3D imaging for improved object and feature inspection. These E-PSFs can be realized in the form of optical phase plates that can be incorporated into existing imaging systems. Once integrated, imaging systems can perform close-range component inspection with improved depth of field and detail, allowing for the imaging and defect detection of smaller...Read full article
