Title: Kevin Yeh: Innovator in Spectroscopic Imaging Technologies
Introduction
Kevin Yeh is a prominent inventor based in Corvallis, OR (US), known for his contributions to the field of vibrational circular dichroism infrared spectroscopic imaging. With a total of 5 patents to his name, Yeh has made significant advancements in imaging technologies that enhance our understanding of molecular structures.
Latest Patents
One of his latest patents is focused on a vibrational circular dichroism infrared spectroscopic imaging microscope. This invention discloses methods and apparatus for obtaining a vibrational circular dichroism (VCD) image using a discrete frequency infrared (DFIR) microscope. The method involves generating a pulsed laser beam with a tunable spectral frequency, modulating the laser beam to create circularly polarized light, and illuminating a sample to collect and detect an optical signal. The detected signal is then demodulated to obtain intensity values corresponding to absorbance and polarization-dependent values related to VCD.
Another notable patent by Yeh is directed towards methods and apparatus for multi-color discrete frequency infrared spectroscopic imaging. This invention includes generating a pulsed laser beam in the mid-infrared region, transmitting it onto a sample, and collecting the emitted optical signal. The raw electric signal is demodulated to obtain intensity values, which are then used to determine pixel values for a DFIR spectroscopic image.
