Title: | Single-shot ultrasound-modulated optical tomography with enhanced speckle contrast | Authors: | Yuan, D Luo, J Wu, D Zhang, R Lai, P Li, Z Shen, Y |
Issue Date: | 1-Jul-2021 | Source: | Optics letters, 1 July 2021, v. 46, no. 13, p. 3095-3098 | Abstract: | Ultrasound-modulated optical tomography (UOT) images optical contrast deep inside biological tissue. Among existing approaches, camera-based parallel detection is beneficial in modulation depth but is limited to the relatively slow framerate of cameras. This condition prevents such a scheme from achieving maturity to image live animals with submillisecond speckle correlation time. In this work, we developed on-axis single-shot UOT by investigating the statistics of speckles, breaking the restriction imposed by the slowcamera framerate. As a proof of concept,we experimentally imaged a one-dimensional absorptive object buried inside a moving scattering medium with speckle correlation time down to 0.48 ms. We envision that this single-shot UOT is promising to cope with live animals with fast speckle decorrelation. | Publisher: | Optical Society of America | Journal: | Optics letters | ISSN: | 0146-9592 | EISSN: | 1539-4794 | DOI: | 10.1364/OL.425535 | Rights: | Journal©2021 Optical Society of America ©2021 Optica Publishing Group.
