摘要:We have developed a photoacoustic (PA) sensor using a low-power, continuous- wave laser and a kHz-range microphone. The sensor is simple, flexible, cost-effective, and compatible with commercial optical microscopes. The sensor enables noncontact PA measurements through air, ...

摘要:Researchers have found that decreased levels of circulating citrulline could be an indicator of intestinal failure. Typically, this amino acid, which is produced by the intestinal mucosa cells, circulates in the blood at a physiological level of ∼40 μM. The current methodolo...

摘要:Live-subject microscopies, including microendoscopy and other related technologies, offer promise for basic biology research as well as the optical biopsy of disease in the clinic. However, cellular resolution generally comes with the trade-off of a microscopic field-of-view. Mic...

摘要:The solution of problems arising in fabrication of optical systems often requires the optimization of a process, design, test, or evaluation related to those systems. There are different optimization techniques that can be used to achieve this goal. In some problems, the par...

摘要:To improve the performance of wireless laser communication (WLC) systems, wavefront sensorless adaptive optics based on deformable mirror (DM) eigenmodes was used to correct the distorted far-field spot. A set of DM eigenmodes conforming to the derivative–orthogonal relation...

摘要:Photoacoustic tomography (PAT) is intrinsically sensitive to blood oxygen saturation (sO2) in vivo . However, making accurate sO2 measurements without knowledge of tissue- and instrumentation-related correction factors is extremely challenging. We have devel...

摘要:Digital image correlation (DIC) is a noncontact technique that is widely used for deformation measurement, but improving the calculation efficiency to achieve real-time DIC calculation has always been a big concern. A parallel temporal sequence DIC method is proposed, which choos...

摘要:Blockage of healthy blood vessels by blood clots can lead to serious or even life-threatening complications. The use of a combined ultrasound (US) and photoacoustic (PA) imaging was explored for blood clot monitoring during microbubble-assisted sonothrombolysis. PA imaging is an ...
