AO-OCT Comes into Focus
Adaptive optics technology is often used to correct for wavefront distortions imparted when light travels through complex optical systems, enhancing image resolution and facilitating diffraction-limited optics. It has played a particularly prominent role in ophthalmic imaging, where retinal tissue imaging is limited by inherent aberrations in the eye.

Dual Imaging Method Holds Promise as a Tool for Cancer Diagnostics
Since Bell Labs first described the photoacoustic effect — the conversion of light to sound — in the late 1800s, researchers have explored the principle for medical imaging purposes. Over the past decade, advancements in lasers, ultrasound transducers, and tomographic reconstruction techniques have prompted immense growth in photoacoustic imaging, a hybrid imaging technology that uses a short-pulse laser to excite tissue.

Novel Multiphoton Imaging Techniques Reveal Brain’s Secrets
Two-photon microscopy has surpassed confocal imaging for the study of intact, living tissue. In essence, two or more low-energy, long-wavelength photons generated off a Ti:sapphire or ytterbium fiber femtosecond laser are absorbed simultaneously by fluorophores expressed in a tissue of interest. The technique allows for wide imaging windows, deep specimen penetration, reduced photobleaching and photodamage, and pinpoint light focusing.

Electrically Tunable Lens (ETL)
Applied Scientific Instrumentation Inc.
ASI’s ETL is a versatile element for a variety of microscopy applications. The ETL can adjust the focal plane of a stationary microscope objective, replacing a focus stage. Using a bare tunable lens introduces significant optical aberrations, but combining the tunable lens with a 4f relay lens system reduces the aberrations to an acceptable level for many applications.

Mobile Device Uses Holographic Analysis, Deep Learning to Detect Parasites
Researchers ave developed an inexpensive, portable platform that can detect motile parasites in bodily fluids rapidly. Using the new platform, more than 3 milliliters (ml) of a bodily fluid sample can be imaged and analyzed within 20 minutes, providing a throughput that is orders of magnitude better than traditional optical microscopy-based examination.

Quantum Dots Are Making Displays Brighter and Photomedicine Better
Tue, Apr 23, 2019 1:00 PM - 2:00 PM EDT
In this webinar you will learn about the properties that make quantum dots (QDs) so desirable in displays, and the types of QD technologies that are most suitable for displays. It will cover strategies for implementing QDs in displays, challenges facing this technology, and QD-enabled displays in the future. In addition to displays, the use of electroluminescent (EL)-QD devices in photomedicine will also be discussed. This webinar is sponsored by Radiant Vision Systems.
