Spatial frequency domain Mueller matrix imaging

December 14, 2022
Author(s)
Joseph Chue-Sang, Maritoni Litorja, Aaron Goldfain, Thomas A. Germer
Significance: Mueller matrix polarimetry (MMP) and spatial frequency domain imaging (SFDI) are wide-field optical imaging modalities that differentiate tissue primarily by structure alignment and photon transport coefficient, respectively. Because these

Polydimethylsiloxane tissue-mimicking phantoms with tunable optical properties

Aaron Goldfain, Paul Lemaillet, David W. Allen, Kimberly Briggman, Jeeseong C. Hwang
We report on techniques to manufacture and characterize solid tissue-mimicking phantoms of polydimethylsiloxane (PDMS) polymers. Tunability of the absorption (a()) and reduced scattering spectra (s'()) in the wavelength range of 500 nm to 850 nm is

Spatial frequency domain Mueller matrix imaging

Joseph Chue-Sang, Aaron Goldfain, Jeeseong C. Hwang, Thomas A. Germer
We combine Mueller matrix polarimetry (MMP) with spatial frequency domain imaging (SFDI) to create a technique that is sensitive to near-surface material anisotropy. We demonstrate this imaging modality with scattering and absorbing phantoms and with a

Dual-comb photoacoustic spectroscopy

Jacob T. Friedlein, Esther Baumann, Kimberly Briggman, Gabriel M. Colacion, Fabrizio R. Giorgetta, Daniel I. Herman, Nathan R. Newbury, Jeeseong Hwang, Ian R. Coddington, Kevin C. Cossel, Gabriel Ycas, Christopher Yung, Eli V. Hoenig, Edgar F. Perez, Aaron Goldfain
Spectrally-resolved photoacoustic imaging is a promising technique for label-free imaging in optically scattering materials. However, this technique often requires acquisition of a separate image at each wavelength of interest. This reduces imaging speeds
