Special Issue Information

Dear Colleagues, 

Optical spectroscopy, sensing and imaging have drawn much attention, owing to the rich interactions of light, including absorption, scattering, and transmission, with particular compounds inside the human body. Some of these optical modalities have been successfully translated to biomedical applications, such as microscopy, endoscopy and optical coherence tomography (OCT), etc. Some of the emerging modalities are still under development, such as photoacoustic imaging, Raman spectroscopy and fiber sensing, etc. This Special Issue will focus on the recent developments and advances in this domain. Both original and review articles are welcome. Reviews should provide a balanced overview of the recent advances in the specified area with a sufficient bibliography. Potential topics include, but are not limited to, the following:

  • Photoacoustic sensing/imaging;
  • Raman spectroscopy;
  • Multispectral sensing/imaging;
  • Fiber sensors;
  • Fluorescence sensing/imaging;
  • Novel biomedical applications.

In recent years, biomedical optics technology has developed rapidly. The current widespread use of biomedical optics was made possible by the invention of optical instruments. The advantages of being non-invasive, portable, effective, low cost, and less susceptible to system noise have led to the rapid development of functional near-infrared spectroscopy (fNIRS) technology for hemodynamics detection, especially in the field of functional brain imaging. At the same time, laboratories and companies have developed various fNIRS-based systems. The safety, stability, and efficacy of fNIRS systems are key performance indicators. However, there is still a lack of comprehensive and systematic evaluation methods for fNIRS instruments. This study uses the fNIRS system developed in our laboratory as the test object. The test method established in this study includes system validation and performance testing to comprehensively assess fNIRS systems' reliability. These methods feature low cost and high practicality. Based on this study, existing or newly developed systems can be comprehensively and easily evaluated in the laboratory or workspace. Full article

Spectrometers are key instruments in diverse fields, notably in medical and biosensing applications. Recent advancements in nanophotonics and computational techniques have contributed to new spectrometer designs characterized by miniaturization and enhanced performance. This paper presents a comprehensive review of miniaturized computational spectrometers (MCS). We examine major MCS designs based on waveguides, random structures, nanowires, photonic crystals, and more. Additionally, we delve into computational methodologies that facilitate their operation, including compressive sensing and deep learning. We also compare various structural models and highlight their unique features. This review also emphasizes the growing applications of MCS in biosensing and consumer electronics and provides a thoughtful perspective on their future potential. Lastly, we discuss potential avenues for future research and applications. Full article
