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…
The objective of this project is to employ Fourier transform infrared spectroscopy (FTIR) in the diagnosis of cancerous lesions and in the chemical characterization of laser-irradiated enamel and dentine. The first subproject will employ FTIR, which is recognized as a useful technique for cancer diagnosis, but in this project it will be associated with paraffin-embedded samples, which are…

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…
LEDs (Light Emitting Diodes) are semiconductors with higher energetic efficiency and can operate with lower voltage and electric current. These characteristics give advantages over conventional illumination. The LED applications are diverse, since signaling (low power) up residential illumination and also are employed for phototherapy in biological applications (high power). Microtiter pl…
