Latest Patents
Li's latest patents include innovative systems designed to enhance the capabilities of laser induced breakdown spectroscopy. The first patent describes a portable laser induced breakdown spectroscopy system. This system comprises a portable device that includes a laser configured to produce a beam with a plurality of repeating pulses. It features a processor that opens a data acquisition window after a delay period, which begins upon the production of one of the pulses. The system also includes optical elements that direct the beam at a sample and collect emitted light from a plasma continuum. An optical detector is configured to produce a plurality of signal values from the emitted light, allowing the processor to identify elements from the signal values.
The second patent focuses on a laser induced breakdown spectroscopy sample chamber. This apparatus includes a sample chamber and a laser source connected to an excitation optics assembly. The excitation optics assembly is linked to a first port on the sample chamber, while a collimator assembly is connected to a spectrometer and a second port on the sample chamber. The design incorporates lens tubes that protect the ports from particles emitted when a laser pulse ablates a target sample surface, generating plasma.
