Accessing depth-resolved high spatial frequency content from the optical coherence tomography signal
Alexandrov, Sergey; Arangath, Anand; Zhou, Yi; Murphy, Mary; Duffy, Niamh; Neuhaus, Kai; Shaw, Georgina; McAuley, Ryan; Leahy, Martin (Nature Research, 2021-08-24)Optical coherence tomography (OCT) is a rapidly evolving technology with a broad range of applications, including biomedical imaging and diagnosis. Conventional intensity-based OCT provides depth-resolved imaging with a ... -
Characterization of an amplified piezoelectric actuator for multiple reference optical coherence tomography
O'Gorman, Sean; Neuhaus, Kai; Alexandrov, Sergey; Hogan, Josh; Wilson, Carol; McNamara, Paul M.; Leahy, Martin (Optica, 2018-08-30)The characterization of an amplified piezoelectric actuator (APA) as a new axial scanning method for multiple-reference optical coherence tomography (MR-OCT) is described. MR-OCT is a compact optical imaging device based ... -
Performance review of multiple reference versus time domain optical coherence tomography
Neuhaus, Kai; McNamara, Paul M.; Alexandrov, Sergey; O'Gorman, Seán; Hogan, Josh; Wilson, Carol; Leahy, Martin J. (IEEE, 2018-04-19)We present a detailed characterization of noise sources in multiple reference optical coherence tomography (MR-OCT) compared to time-domain OCT (TD-OCT). The noise characteristics were modeled based on the TD-OCT noise ... -
Simple characterization scheme for optical coherence tomography systems with application to a commercial and a near-isometric resolution fibre-based system
Dey, Rajib; Zhou, Yi; Neuhaus, Kai; Alexandrov, Sergey; Nolan, Andrew; Chang, Ting-Chiao; Leahy, Martin (2021-12-14)Optical Coherence Tomography (OCT) is a rapidly growing imaging modality in biomedical optics. OCT can perform high-resolution, cross-sectional imaging of the microstructure of biological tissues by measuring the coherent ... -
Simultaneous en-face imaging of multiple layers with multiple reference optical coherence tomography
Neuhaus, Kai; O’Gorman, Seán; McNamara, Paul M.; Alexandrov, Sergey; Hogan, Josh; Wilson, Carol; Leahy, Martin J. (Society of Photo-optical Instrumentation Engineers, 2017-08-22)A technique based on multiple reference optical coherence tomography (MR-OCT) is proposed for simultaneous imaging at multiple depths. The technique has been validated by imaging a reference sample and a fingerprint in-vivo. ...
