Significance of Photonics in Healthcare

Photonics encompasses all light-related sciences and technologies.

FREMONT, CA: Innovating in an expanding range of disciplines is made possible in large part by photonics. The use of photonics is widespread in many industries, including manufacturing, life sciences, health care, security, and safety, as well as optical data transmission, imaging, lighting, and displays.

Photonics in disease diagnosis: Photonics technologies have been employed during the last two decades to identify disease-specific biomarkers, metabolites, metabolic biomarkers, infections, and disease-specific alterations in the composition of cells, tissues, and bodily fluids.

In current optical imaging techniques, a laser is used to send light into a tissue. Optics or electro-optical sensors detect light diffraction, refraction, scattering, and absorption by the tissue.

Photonics in disease treatment: Light scattering and absorption are studied to learn more about malignancies at the cellular and subcellular levels. Ultra-short laser bursts for tissue incisions reduce lengthy surgical procedures, blood loss, and surgery-related discomfort.

Optical propriety of cells: Precision and accuracy in measuring the visual characteristics of materials are critical for the evolution of optical technology and applications. Reflectance, transmittance, emittance, absorptance, and index of refraction are examples of such metrics.

Another imaging technique used to quantify refractive index dispersion within cells is optical diffraction tomography. The tomographic technique is critical for deducing refractive index distribution from phase imaging optical thickness.

Quantitative phase imaging produces two-dimensional phase pictures for three-dimensional tomographic reconstruction.
