PI (Physik Instrumente) says that its new PILightning search-and-alignment algorithm represents a breakthrough in optimizing the alignment of optical components. Before that process can start, an optical signal, above the noise level, must be registered in a procedure called first-light detection. PILightning, the newest functionality in PI’s photonics-process-automation suite, is a first-light search method with an integrated artificial-intelligence-based real-time executive function. Replacing fine-pitch scanning with high-frequency data sampling, it significantly raises acquisition speeds. Tests have shown improvements of one order of magnitude and more in single-sided alignment applications; higher gains are achieved in double-sided first-light detection applications. PILightning has the potential to lower costs for test and assembly in industrial photonic-alignment applications, from wafer probing to final packaging.
