ABSTRACT:The study of the optical properties of the skin has lead to the identification of the main chromophores such as hemoglobin and melanin. Melanin is a chromophore of the skin, whose accumulation in its different layers defines the types of melanocytic lesions (nevus). In order to achieve the reconstruction of acquired melanocytic lesions, the optic tomography of multispectral skin images was constructed by using a plugin created under the ImageJ environment. This plugin demonstrates the iconographic overlap of images, by capturing segmented images (by multispectral bands), called the multispectral cube of the skin. This 3D image allowed to verify the location of the main chromophores of each layer by its relation to the histopathological location. With this method, the melanin pigment localization patterns (melanin nests) were defined in real time and the structural alterations of nevic skin lesions, that would otherwise not be visible without biopsy, could be defined. The method we present has been shown very useful for for locating the chromophores of the skin.Key words: Multispectral, Skin, Photodiagnostic RESUMEN:Al estudiar las propiedades ópticas de la piel, se han identificado los principales cromóforos como son: la hemoglobina y la melanina. La melanina es un cromóforo de la piel, cuya acumulación en sus diferentes capas define los tipos de lesiones melanocíticas (nevus). Con la finalidad de lograr la reconstrucción de imágenes de lesiones melanocíticas adquiridas, se construyó la tomografía óptica de imágenes multiespectrales de piel mediante un plugin creado bajo el entorno ImageJ, que demuestra el solapamiento iconográfico de imágenes, mediante captura de imágenes segmentadas (por bandas multiespectrales), llamado cubo multiespectral de la piel. Esta imagen 3D permitió verificar la localización de los principales cromóforos de cada capa de la misma, al relacionarlas con la localización histopatológica. Con este método se definieron los patrones de ubicación de pigmento melánico (tecas de melanina), en tiempo real y se pudieron definir las alteraciones estructurales de lesiones névicas de piel que de otra forma no serían visibles, sin la toma de la biopsia. Este método se ha demostrado de gran utilidad para la localización de los cromóforos de la piel.

“…The technique obtains the spatial and spectral information in the interested field based upon collection of a complete spectrum at every location of an imaging scene by scanning it visually and in wavelength ranges from the UV to long-wave IR [26]. Here, optomechatronic spectral dispersive devices are used to separate the wavelengths of light, which include tunable gratings, filters such as acousto-optic filter and LC filter, prisms, and interferometers as shown in Figure 4.…”

Abstract. The use of optomechatronic technology, particularly in biomedical optical imaging, is becoming pronounced and ever increasing due to its synergistic effect of the integration of optics and mechatronics. The background of this trend is that the biomedical optical imaging for example in-vivo imaging related to retraction of tissues, diagnosis, and surgical operations have a variety of challenges due to complexity in internal structure and properties of biological body and the resulting optical phenomena. This paper addresses the technical issues related to tissue imaging, visualization of interior surfaces of organs, laparoscopic and endoscopic imaging and imaging of neuronal activities and structures. Within such problem domains the paper overviews the states of the art technology focused on how optical components are fused together with those of mechatronics to create the functionalities required for the imaging systems. Future perspective of the optical imaging in biomedical field is presented in short.
