A space camera optical system based on an off-axis four-mirror freeform design is one such solution, offering a 70° ultra-wide field of view from a 640 km orbital altitude. This system is an ideal ...

For example, a 0.71x telecompression factor delivers an effective aperture gain of approximately one stop. This means that the system is able to operate at lower ISO values or higher shutter speeds, ...

Intravital mesoscale imaging plays a crucial role in bridging the gap between cellular and organ-level investigations by enabling high-resolution visualization across large fields of view. Continuous ...

Diffuse optical spectroscopy and imaging have emerged as versatile techniques for investigating the optical properties of complex media, particularly in biomedical, environmental and agricultural ...

Skin cancer is the most common form of cancer worldwide, and early detection is key to successful treatment. While traditional methods rely on visual inspection and biopsy, researchers are developing ...

Hui Wang, Ph.D., associate professor of Chemical, Paper, and Biomedical Engineering, has recently been awarded a new grant of approximately $200,000 from the National Institute of Biomedical Imaging ...

Researchers from the University of Science and Technology of China (USTC) have unveiled a planar optical device that significantly enhances the capabilities of dark-field microscopy, achieving ...

Optical coherence tomography (OCT) is an imaging technology that can non-invasively generate cross-sectional images of tissue. OCT is widely used in eye clinics to diagnose and manage retinal diseases ...

In a recent study published in the journal Nature Biomedical Engineering, researchers developed a three-dimensional (3D) photoacoustic tomography (PAT) scanner for rapid vascular imaging. Visualizing ...

Colorectal cancer (CRC) is one of the most common and deadly forms of cancer worldwide. A key reason for its high death toll is that it often goes undetected until it reaches an advanced stage.

Thyroid cancer is the most common endocrine cancer, affecting more people each year as detection rates continue to rise. During tumor excision, surgeons often struggle to determine exactly how much ...
