    • The invention features methods and systems for selectively delivering or coupling laser radiation into a first material or substrate, e.g., a first biological tissue, having a first index of refraction and not into a second material or substrate, e.g., a second biological tissue, having a second index of refraction. The system determines whether a target area corresponds to the first material or the second material by monitoring the reflection of a probe beam incident on the target area through an optical coupler at a non-normal incident angle. The monitored reflection of the probe beam is a control signal for a feedback controller that causes a treatment beam to be delivered to the target area based on the monitored reflection.
    • 本发明的特征在于用于选择性地将激光辐射输送或耦合到第一材料或基底(例如,具有第一折射率的第一生物组织)的方法和系统,而不是第二材料或基底,例如第二生物组织,其具有 第二折射率。 该系统通过以非正常入射角通过光耦合器监测入射在目标区域上的探测光束的反射来确定目标区域是否对应于第一材料或第二材料。 探测光束的监视反射是反馈控制器的控制信号,该反馈控制器基于所监视的反射将治疗光束输送到目标区域。
