1. Predição e identificação de danos internos em batatas por meio do biospeckle laser / Prediction and identification of potatoes in internal damagethrough the laser biospeckle
Food damages due to mechanical impacts at post harvest different phases are one of the biggest issues faced by food industry. In potatoes, productivity decrease due to impacts and physical damages can get to 40% during processing, storage, transportation and commercialization phases. Intern injuries, or bruising, are one of the biggest factors losses at pota

2. Estudo e desenvolvimento de simuladores de tecido humano para utilização em fototerapia / Study and development human tissue phantoms for fototherapy
Uma das dificuldades da dosimetria na área de Terapia com Laser de Baixa Intensidade (TLBI) é conhecer a distribuição da luz nos tecidos biológicos. Esse conhecimento pode ser obtido com o uso de materiais que simulem as características ópticas dos tecidos. O objetivo desse trabalho é produzir e avaliar simuladores (phantoms) sólidos em formato seme

3. AnÃlise de Resposta em FrequÃncia do Biospeckle Laser / Frequency analysis of the biospeckle laser.
This work presents a study of the interaction of the laser light with tissue of beans seeds (Phaseolus Vulgaris L.). It is a contribution for the development of biospeckle technique applied to recognition of alive tissues of beans seeds contaminated with fungi and its differentiation by the frequency specter. Biospeckle is an interference optic phenomenon th

4. Efeito do grau de coerencia da luz laser na cicatrização de lesão cutanea experimental
The present work shows experimental data confirming the importance of light coherence in the process of wound healing stimulated by lasers. The results were obtained through a comparativa study of biostimulating effects obtained by the use of laser light and laser light with low degree of coherence. In this study we use standardized lesions resulting from th
