Compared with traditional detection methods, OCT has high resolution, no harm to samples, and can obtain real-time measurement results of the sample.  Optical Coherence Tomography (OCT) is a new imaging technique based on low coherence measurement. It can perform non-contact and non-invasive tomography of living tissue microscope structures. OCT is an optical analog of ultrasound with higher longitudinal resolution and does not adversely affect organisms like X-rays and RF electromagnetic fields.Therefore, OCT is particularly suitable for samples with high scattering and non-transparent properties, and organisms are such samples.At present, more and more OCT is applied to the diagnosis of biological tissues, especially the diagnosis of ophthalmology and subcutaneous tissue.

说明: Researchers at Purdue University have developed a new technology—a roll-to-roll laser-induced superplasticity process that can be used to print ultra-fast nanoscale electronic devices.This process is similar to the roll-to-roll printing process of newspaper printing, which can produce smoother, softer metal lines for the production of high-speed electronic devices, greatly increasing the production speed of electronic devices.Mobile phones, laptops, tablets, and many other electronic devices rely on their internal metal circuitry for high-speed processing of information. Current metal circuit fabrication methods generally involve forming a metal line by passing a thin liquid metal droplet through a reticle having a target line shape, which is somewhat like graffiti on a wall. However, the metal lines produced by this technology have a very rough surface, which causes the electronic device to heat up more quickly, thereby draining the battery faster.Future high-speed electronic devices ...
