Tang Z, Winnik J, Hennelly B
Biomed Opt Express . 2025 Jan; 16(1):57-67. PMID: 39816153
Optical diffraction tomography enables label-free, 3D refractive index (RI) imaging of biological samples. We present a novel, cost-effective approach to ODT that employs a modular design incorporating a self-reference holographic...

Yu Q, Hennelly B
J Opt Soc Am A Opt Image Sci Vis . 2024 Jun; 41(5):920-931. PMID: 38856578
Using the flux tracing algorithm developed in the previous two parts, we examine the nonlinear rays that pass through the focus of a lens containing monochromatic aberrations. Lens aberration is...

Yu Q, Hennelly B
J Opt Soc Am A Opt Image Sci Vis . 2024 Jun; 41(5):906-919. PMID: 38856577
In this three-part paper series, we develop a method to trace the lines of flux through a three-dimensional wavefield by following a direction that is governed by the derivative of...

Liu D, Hennelly B
Appl Spectrosc . 2024 Jun; 78(8):790-805. PMID: 38825581
A wavenumber calibration protocol is proposed that replaces polynomial fitting to relate the detector axis and the wavenumber shift. The physical model of the Raman spectrometer is used to derive...

Liu D, Hennelly B
Appl Spectrosc . 2022 Jun; 76(11):1283-1299. PMID: 35726593
Wavelength calibration is a necessary first step for a range of applications in spectroscopy. The relationship between wavelength and pixel position on the array detector is approximately governed by a...

ODwyer K, Domijan K, Dignam A, Butler M, Hennelly B
Cancers (Basel) . 2021 Oct; 13(19). PMID: 34638253
Raman micro-spectroscopy is a powerful technique for the identification and classification of cancer cells and tissues. In recent years, the application of Raman spectroscopy to detect bladder, cervical, and oral...

Fan X, Healy J, ODwyer K, Hennelly B
Appl Opt . 2019 May; 58(12):3104-3114. PMID: 31044784
Modern microscopes are designed with functionalities that are tailored to enhance image contrast. Dark-field imaging, phase contrast, differential interference contrast, and other optical techniques enable biological cells and other phase-only...

Barton S, Hennelly B
Appl Spectrosc . 2019 Apr; 73(8):893-901. PMID: 31008665
Cosmic ray artifacts may be present in all photo-electric readout systems. In spectroscopy, they present as random unidirectional sharp spikes that distort spectra and may have an affect on post-processing,...

Tang Z, Barton S, Ward T, Lowry J, Doran M, Byrne H, et al.
Appl Opt . 2018 Aug; 57(22):E118-E130. PMID: 30117908
Measuring the concentration of multiple chemical components in a low-volume aqueous mixture by Raman spectroscopy has received significant interest in the literature. All of the contributions to date focus on...
