“…In addition, we apply a tiny drop of honey to the healthy skin as a phantom for small skin patches with varying optical activity. 38 Aligning these samples is particularly important due to their strong contrast resulting from the hair and the nevus. The clinical and dermoscopic images serve as reference for the polarimetric skin imaging.…”

. Significance: Mueller matrix (MM) polarimetry is a promising tool for the detection of skin cancer. Polarimetric in vivo measurements often suffer from misalignment of the polarimetric images due to motion, which can lead to false results. Aim: We aim to provide an easy-to-implement polarimetric image data registration method to ensure proper image alignment. Approach: A feature-based image registration is implemented for an MM polarimeter for phantom and in vivo human skin measurements. Results: We show that the keypoint-based registration of polarimetric images is necessary for in vivo skin polarimetry to ensure reliable results. Further, we deliver an efficient semiautomated method for the registration of polarimetric images. Conclusions: Image registration for in vivo polarimetry of human skin is required for improved diagnostics and can be efficiently enhanced with a keypoint-based approach.

“…Desde el punto de vista químico, la miel es una solución sobresaturada de azúcares, que tienden a precipitarse; es decir, a formar cristales sólidos según las proporciones de glucosa, fructosa y agua [3]. Debido a esto, se ha demostrado que, empleando luz polarizada, es posible realizar una caracterización de esta [4].…”

In the teaching-learning process at the upper and upper secondary levels, it is difficult to motivate students about the importance of knowing and applying basic concepts in industrial processes. Therefore, it is proposed how to apply the concept of light polarization and spectroscopy to visualize the differences between substances based on sucrose or fructose. Both techniques have been applied in various industrial processes; their cost is regularly high and require extensive training. In this paper, we present the results of the implementation of a low cost linear polariscope for the analysis of natural bee honey and syrups based on sucrose. The arrangement consists of a semiconductor laser, a photodiode, two polarizers, a stepper motor and some mechanical elements, all controlled by the computer through a graphical interface. To validate the results, an optical array based on a low-cost commercial spectroscope is used. By implementing this experimental arrangement, the concepts of polarization, optical activity, atomic-molecular physics, electronic instrumentation and principles of equipment design and construction are involved.
