Design, construction, and characterization of an ultra-sensitive, high-precision fast ion-beam spectrometer for the study of molecular ions
… absorption spectra of molecular ions. It is the first work to use the noise immune cavity-enhanced optical heterodyne molecular spectroscopy (NICE-OHMS) technique in conjunction with a fast ion beam. Additionally, it is the first work outlining direct electronic spectroscopy in an ion beam. Direct …

Nanostructured Devices for Ultrasensitive and High Throughput Vibrational Spectroscopic Imaging
… in vibrational spectroscopic imaging. First, Surface-enhanced Raman scattering (SERS)-based substrates will be discussed and nanostructured particle probes are proposed. Their optical tunability with structure is discussed in detail and preliminary fabrication and validation are …

Mid infrared spectroscopic imaging and tomography
Fourier Transform Infrared (FT-IR) Spectroscopic Imaging is an optical technique that simultaneously provides morphological (two dimensional) and mid-infrared spectral (one dimensional) information for a specimen under observation. In this dissertation, we develop a new instrument that extends the …
