Photoacoustic microscopy (PAM) is a relatively new imaging technique that uses laser light to induce ultrasonic vibrations in tissue. These ultrasonic vibrations, along with a computer that processes ...

In photography, depth of field refers to how much of a three-dimensional space the camera can focus on at once. A shallow depth of field, for example, would keep the subject sharp but blur out much of ...

Extended depth of field imaging systems represent a significant advancement in optical design, enabling sharp imaging over a broader range of distances. By incorporating methods such as wavefront ...

Researchers at the University of Tartu's Institute of Physics have developed a new technique to improve the quality of ...

Researchers have developed a new method for flexibly creating various needle-shaped laser beams. These long, narrow beams can be used to improve optical coherence tomography (OCT), a noninvasive and ...
