Latest Patents
One of Sang H Choi's notable patents is the "Deployable Micro-Spectrometer Bullets." This invention describes a tiny and portable micro-spectrometer that can be deployed in a bullet-like form. The device is designed to be inexpensive, to the point that it can even be disposable. It operates based on the Fresnel diffraction principle, allowing for a tiny implementation with a nanometer resolving power of spectral signals. The micro-spectrometer integrates a super capacitor as a power source, a charging coil, an LED or laser diode light source, an analog to digital converter (ADC) circuit, and a telemetry system with an antenna string. The LED or laser diode operates in burst mode to generate deep or vacuum UV light to excite target materials. The resulting fluorescence or luminescence from the excited state of the target material is then sensed by the micro-spectrometer to identify the spectral signature of the material. The data collected is converted by the ADC and transmitted to a receiving station.
