The anomalies typification in human tissues, including neoplasms, is usually performed by histological examinations on slides containing biopsies. Research on digital biopsy images has grown rapidly, leveraging the development and improvement of image processing methods specially developed or adapted for this category of images. The hyperspectral signals, obtained using infrared equipment…
Measure the tissue optical properties are fundamental for clinical phototherapy. Unknown the absorption and scattering coefficients or the optical penetration depth decreases the guarantee in processing the correct optical dosimetry of clinical systems. The solution is employ methodologies who measure the parameters accurately and preferentially in vivo and noninvasively. The objective is…

Background: Although photobiomodulation therapy (PBMT) is extensively investigated, the therapeutic procedures involving light irradiation are not yet fully understood within the scientific community. Among relevant factors, biological individualities, such as melanin concentration, emerge as significant confounders. Consequently, different responses can be observed even in health conditi…
This work aims to address and understand the optical properties of biological tissues, grounding the study in the propagation of optical radiation in turbid media. Among the properties studied are absorption and scattering coefficients, anisotropy factors, refractive index, albedo, and derived parameters such as reduced scattering, in addition to the effective attenuation coefficient and …
Many material properties can be determined using the basic processes of optical phenomena,such as reflection, transmission, absorption, fluorescence and scattering. Spectral characterization of light sources is of great importance, as it measures the spectral distribution of radiation,such as the measurement of spectral irradiance (W/m2/nm). The colorimetric quantities are calculated usin…

Although the optical properties of biological tissues have been widely reported in the literature, we need a better understanding of how light propagates these media, especially considering different types of light sources. Thus, the present work aims to simulate the propagation of optical radiation on the skin using Monte Carlo simulations. We will consider in these simulations the optic…
The measurement and monitoring of solar spectral irradiance, in particular that which is accounted for when calculating the UV Index, is highly useful for researchers of numerous fields and variable proficiencies in manipulation and maintenance of spectroscopy instruments. However, there is currently a noticeable scarcity of specialized equipment for such measurements, and specially of in…
The project will employ FTIR (Fourier transform infrared spectroscopy) and a progressive enamel wear to monitor the chemical composition at subsurface of the enamel after irradiation with CO2 laser (10.6 ¼m) using 3 irradiation parameters: 3 J/cm2 /5¼s; 1,25 J/mm2 /20¼s; 1,63 J/mm2 /33¼s. The analysis will evaluate the extension of laser action on enamel, such as carbonate loss, water los…
