Abstract:
A system for analyzing an object, the system having first and second operating modes, the system comprising:a laser operable to radiate a beam of radiation;an objective lens operable to focus the beam on the object and gather radiation reflected from the object;a beam scanner optically coupled to the laser to receive the beam from the laser, the beam scanner configured to output the beam towards the objective lens, the beam scanner configured to scan the beam in the first operating mode;a reflector system operable to direct at least a portion of the radiation reflected from the object along a first return path in the first operating mode, the reflector system being further operable to direct at least a portion of the radiation reflected from the object along a second return path in the second operating mode;a sensor positioned in the first return path, the sensor being configured to detect intensity levels of the radiation reflected from the object in the first operating mode;a spectrometer having a radiation reception portion positioned in the second return path, the spectrometer being configured to define wavelength spectrum characteristics of the radiation reflected from the object in the second operating mode;an aperture optically coupled between the laser and the objective lens, the aperture being positioned in the first return path between the reflector system and the sensor, the aperture being positioned outside the second return path.
