Latest Patents

Changmin Ahn holds a patent for an ultrafast camera system and measurement method. This system includes a sensor head that injects an optical pulse train from a pulsed laser onto a measurement target's surface. It outputs an optical signal reflected from the surface. Additionally, a timing detector receives the optical signal, which has undergone a time-of-flight change after passing through the sensor head. The detector outputs an electrical signal corresponding to the timing error between the optical signal and a reference signal. Another version of the ultrafast camera system incorporates a wavelength dispersion device that disperses the optical pulse train into a wavelength spectrum. A lens vertically injects the continuous wavelength signals onto a measurement line, while the timing detector measures the timing error between the reference signal and the continuous wavelength signals.
