Abstract

"PROCESSO E DISPOSITIVO PARA DETECTAR E LOCALIZAR CAMADAS DE REFLEXãO DIFUSA, PRESENTES EM VIDRO TRANSPARENTE". O problema técnico é solucionado neste caso ao se detectar sem contato quaisquer camadas de reflexão difusa e diferenciar entre camadas na superfície voltada para o sensor e camadas na superfície afastada do sensor. Isso é possível pelo fato do processo compreender basicamente a captação da imagem de um objeto por meio de uma unidade de detecção, fazendo parte do dispositivo, mediante a inclusão do vidro na trajetória do raio que se estende desde o objeto até a unidade de detecção e a avaliação correspondente da informação de imagem.
