Journal ArticleDOI
Deep non-contact photoacoustic initial pressure imaging
TL;DR: Deep photoacoustic remote sensing (dPARS) as discussed by the authors uses visible pulsed excitation wavelengths to produce large initial pressure-induced refractive index modulations in absorbing targets, which are detected as back-reflected intensity modulations from a deep-penetrating interrogation beam.

Photoacoustic remote sensing (pars)
Parsin Haji Reza,Roger J. Zemp +1 more
TL;DR: A photoacoustic remote sensing system (PARS) for imaging a subsurface structure in a sample has an excitation beam configured to generate ultrasonic signals in the sample, an interrogation beam incident on the sample at the excitation location, a portion of the interrogation beam returning from the sample that is indicative of the generated ultrasonic signal as discussed by the authors.
Journal ArticleDOI
Towards non-contact photoacoustic imaging [review].
TL;DR: This paper presents a brief overview of current non-contact photoacoustic detection techniques with an emphasis on all-optical detection methods and their associated physical mechanisms.
Journal ArticleDOI
All-optical Reflection-mode Microscopic Histology of Unstained Human Tissues.
Saad Abbasi,Martin Le,Bazil Sonier,Deepak Dinakaran,Gilbert Bigras,Kevan Bell,John R. Mackey,Parsin Haji Reza +7 more
TL;DR: Here, the first microscopy capable of non-contact label-free visualization of human cellular morphology in a reflection-mode apparatus is presented, and clinically useful histologic images of human tissue samples including breast cancer, tonsil, gastrointestinal, and pancreatic tissue images were formed.
Journal ArticleDOI
Chromophore selective multi-wavelength photoacoustic remote sensing of unstained human tissues.
Saad Abbasi,Martin Le,Bazil Sonier,Kevan Bell,Deepak Dinakaran,Gilbert Bigras,John R. Mackey,Parsin Haji Reza +7 more
TL;DR: A non-contact multi-wavelength reflection-mode, photoacoustic remote sensing (PARS) microscope demonstrating chromophore selective contrast in human tissues is developed, providing a critical step towards a virtual histology tool to provide intraoperative histology-like information in living tissue.
