Optical Advancements Enable High-Precision 3D Imaging
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 (Figure 1). Figure 1. An optical phase plate in its holder, with point
