Auto-aligning spectroscopy system

摘要

An auto-aligning system (100) is presented. One embodiment of the auto-aligning system (100) includes a launcher unit (104) configured to direct a first laser beam (118) and a second laser beam (120) through a chamber (102), wherein the first laser beam (118) is co-linear with the second laser beam (120). The auto-aligning spectroscopy system further includes a receiver unit (106) configured to receive the first laser beam and the second laser beam (144) passing through the chamber. The receiver unit (106) includes a first detector (134) configured to determine an intensity of the first laser beam (148). The receiver unit (106) also includes a second detector (136) configured to determine a deviation of the second laser beam (150) from a determined position (202). Further, the auto-aligning spectroscopy system includes a motorized stage (112) configured to align the launcher unit (104) to a base-line position based on the determined deviation of the second laser beam (120).
