Abstract: An actively Q-switched laser induced breakdown spectroscopy (LIBS) probe, utilizing an optical fiber, a pump beam transmitted through the optical fiber, a coupler, and a lens for collimating the pump beam. The actively Q-switched laser, coupled to a sensor which provides information to a computer that controls a high voltage pulser providing a pulse to a Pockels cell located within the laser which can selectively cause the laser to pulse, resulting in high energy pulses and a second lens for focusing the output pulse such that it creates a plasma or spark. The light from the spark is captured and directed back through an optical system to remote equipment for elemental and/or molecular analysis.

Abstract: An optical system operating in the near or short-wave infrared wavelength range identifies an object based on water absorption. The system comprises a light source with modulated light emitting diodes operating at wavelengths near 1090 and 1440 nanometers, corresponding to lower and higher water absorption. The system further comprises one or more wavelength selective filters and a housing that is further coupled to an electrical circuit and a processor. The detection system comprises photodetectors that are synchronized to the light source, and the detection system receives at least a portion of light reflected from the object. The system is configured to identify the object by comparing the reflected light at the first and second wavelength to generate an output value, and then comparing the output value to a threshold. The optical system may be further coupled to a wearable device or a remote sensing system with a time-of-flight sensor.

The module includes an excitation fiber and parallel collection fibers surrounding a periphery thereof. The magnifying lens group includes sequentially-arranged convex lenses. The detection window is located near an object-distance position of a lens close to a detection end. A distance between two adjacent convex lenses is equal to a sum of former's image distance and latter's object distance. Focal lengths of the convex lenses in the magnifying lens group are f, and satisfy a ratio of the object distance to the image distance of n:1, and a length L of the magnifying lens group satisfies:

Abstract: Optical systems have uses, such as in spectrometers, for directing a beam. A spectrometer, for example, utilizes an optical system for directing an incident beam toward a sample and receiving a spectroscopy signal from the sample. In various implementations, for example, an optical system may be further configured to move a beam with respect to a target, such as a sample, and still provide a home position where the beam is directed in a stationary configuration. A self-homing (e.g., self-centering) optical system may provide a “home” position in which the beam is directed in a first stationary mode while still allowing a focused beam to be moved with respect to a target in a second dynamic mode.
