Latest Patents

Yongwoo Park holds a patent for a groundbreaking invention titled "Cross-chirped interferometry system and method for light detection and ranging." This patent describes an interferometric method and system that enables the mapping of light echoes into a spectrum. The technology has multiple applications, including laser rangefinding, biomedical imaging such as surface 3D mapping and tomography, vehicle position identification, and spectrum analysis.

The innovation allows direct mapping into the spectrum, facilitating time-of-flight detection without the need for timing pulse modulation. Its sensitivity matches that of conventional low coherence interferometry, delivering an eye-safe and cost-effective solution that does not compromise performance. This system enables high-accuracy range detection, comparable to traditional laser rangefinders, achieved with a timing pulse of just 20 picoseconds Full-Width-at-Half-Maximum (FWHM).

The core of his invention revolves around the application of dispersion-unbalanced interference, referred to as 'cross-chirp interference,' combined with the gating of phase-matched spectral components. As the dispersion unbalance increases, so does the system's performance in terms of range and resolution.
