Patent ID: 8711340

Claim:
An auto-aligning spectroscopy system, comprising: a launcher unit configured to direct a first laser beam and a second laser beam through a chamber, wherein the first laser beam is co-linear with the second laser beam; a receiver unit configured to receive the first laser beam and the second laser beam passing through the chamber, wherein the receiver unit comprises: a first detector configured to determine an intensity of the first laser beam; a second detector configured to: generate at least two signals indicative of a first position of the second laser beam incident on the second detector, wherein the first position is different from a determined position; generate at least one signal indicative of a power associated with the second laser beam; determine a deviation of the second laser beam from the determined position; a controller unit configured to: determine a power loss of the second laser beam based on the power associated with the second laser beam; compare the determined power loss of the second laser beam with a determined threshold value; identify a scattering of the second laser beam when the power loss of the second laser beam is less than the determined threshold value and there is no deviation of the second laser beam from the determined position; and a motorized stage configured to align the launcher unit to a base-line position when the power loss of the second laser beam is greater than the determined threshold value.
