Refractive angles for a given input angle, optical shape and index values are pre-calculated and printed onto a template. Consequently, CRI, especially its imaginary part, is a very useful optical parameter by which to evaluate the OC effect. The refractive index can be measured with a laser line and a template. The change tendency of the extinction coefficient of tissue is used to qualitatively explain the dynamic change of transmittance of a natural dehydrated tissue. Finally, the extinction coefficient becomes much smaller than the initial value, which demonstrates that better tissue optical clarity is obtained. While swelling gelatin particles can provide a site for a fibrin clot to limit blood flow and form a mechanically stable matrix around this bleeding site 42, 68. Gelatin and thrombin can act as a stable clot at the bleeding site. Results show that the real RI increases continuously with the increase of dehydration time, whereas the extinction coefficient initially increases and then decreases. Gelatin is very important in the field of medicine such as haemostasis (preventing bleeding). Based on the total internal reflection method, the time-dependent CRI of porcine muscle during natural dehydration is well determined. From the imaginary part of CRI, we can deduce the extinction coefficient of tissue. The refractive index can be measured with a laser line and a template. 187, the average refractive index of human skin undergoes significant changes, over 10, when. photocrosslinked porcine gelatin, photocrosslinked bovine fibrinogen. Unfortunately, this method is relevant only for soft tissues. Monitoring the changes of optical parameters, including the complex refractive index (CRI), helps people better understand the OC process. characteristics such as transparency and a refractive index similar to the cornea. The physical changes of tissue are complicated to evaluate during optical clearing (OC) treatment.
