IR Metrology with Visible Light
A new approach to IR metrology uses common optical components for the visible range. The technique is based on nonlinear interference of correlated photons, in which information about the photon in the IR range is inferred from the measurement of its correlated photon in the visible range. Applications for spectroscopy and optical coherent tomography (OCT) are discussed in this article.

NIRS Surpasses Conventional Diagnostics for Orthopedics
Early diagnosis of musculoskeletal diseases is vital for effective treatment. To prevent disease progression, endoscopy-guided surgeries are performed to repair torn ligaments, the meniscus, and damaged cartilage. A potential solution for objectively assessing joint tissue conditions during arthroscopy is the use of optical spectroscopy, such as near-IR spectroscopy (NIRS).

Multispectral Imaging Aids Wound Healing, Pathology Research
From airborne mapping to astronomical imaging to manufacturing inspection, multispectral imaging (MSI) has long been the go-to tool for extracting crucial details, often from distant views. Today, MSI is making promising inroads in biomedical applications, where its capacity for noninvasive, cost-effective imaging delivers customizable information in real time.

MIR Upconversion Imaging Could Speed Medical Diagnostics
Researchers from multiple institutions collaborated to develop a way to translate information from the mid-infrared (MIR) region, where chemical signatures are most distinct, to the near-infrared (NIR), where existing camera technology is most sensitive. Their new, wide field-of-view system can capture MIR spectral images of fast events or dynamic processes that take place in a matter of milliseconds.

New Class of Visible-Light Photoswitches Could Provide Greater Molecular Photocontrol
A consortium of scientists from five European institutions has developed a new class of molecular photoswitches that are operated with visible light only. The new switches show large separation of absorption bands and function in various solvents including water. The researchers believe that the new switches could lead to the development of improved photocontrolled systems for a variety of applications that require fast, responsive functions.
