Ultrasound-modulated optical tomography (UOT) is a technique that images optical contrast deep inside scattering media. Heterodyne holography is a promising tool that is able to detect UOT-tagged photons with high efficiency. In this work, we describe theoretically the detection of the tagged photon in heterodyne holography-based UOT, show how to filter the untagged photon, and discuss the effect of shot noise. The discussion also considers speckle decorrelation. We show that optimal detection…

A new approach to diffuse correlation spectroscopy which overcomes the limited light throughput of single-mode photon counting techniques is presented, and the feasibility of the system is demonstrated through in vivo measurement of pulsatile flow rates measured in the human forearm.

Imaging speckle decorrelation effect with combined acousto-optical imaging with off-axis heterodyne holography for biomedical applications

Using off-axis heterodyne holography, we present acousto-optical measurements of two phantoms: a silicon (no decorrelation) and a gel phantom (decorrelation). Decorrelation of the two media show…

Imaging blood flow inside highly scattering media using ultrasound modulated optical tomography

The use of ultrasound modulated optical tomography with heterodyne parallel detection to locally sense and image blood flow deep inside a highly scattering medium and an analytical model that relates UOT signals to the optical properties of the blood and the background medium is presented.

Ultrasonic Modulation of Coherent Light in Raman–Nath Diffraction

This paper analyzes the ultrasonic modulation of coherent light in Raman–Nath acousto-optic diffraction. We find that the frequency shifts of the diffracted light cause the periodic variation of the…

Dependences of ultrasonic modulation of coherent light on optical frequency shift and phase modulation

In ultrasound-modulated optical tomography, the incident light is frequency-shifted and phase-modulated simultaneously by ultrasound. Both the optical frequency shift and phase modulation can cause…

Lock-in camera based heterodyne holography for ultrasound-modulated optical tomography inside dynamic scattering media.

Compared with the conventional four-frame based amplitude measurement method, the single-frame UOT method is more immune to speckle decorrelation and promising for in vivo deep tissue non-invasive imaging.

Photorefractive detection of tagged photons in ultrasound modulated optical tomography of thick biological tissues.

Pulsed ultrasound modulated optical tomography with harmonic lock-in holography detection.

A method that uses digital heterodyne holography reconstruction to extract scattered light modulated by a single-cycle ultrasound (US) burst is demonstrated and analyzed and it is shown that the modulated signal can be maximized by selecting a pulse sequence which consists of a pulse followed by its inverted counterpart.
