Abstract

SISTEMAS E MÉTODOS PARA DISCRIMINAÇÃO DE ALVOS EM TECIDOS. A presente invenção refere-se a sistemas e métodos para detectar amostras e outros compostos de interesse. O sistema pode incluir uma fonte de iluminação que está configurada para emitir luz em uma variedade de diferentes de bandas de comprimento de onda, um filtro óptico, um chip de câmera, e um percurso óptico configurado para direcionar a luz emitida pela primeira fonte de iluminação em um alvo e direcionar a luz refletida do alvo para o pelo menos um chip de câmera. A fonte de iluminação e o filtro óptico são transicionáveis entre um primeiro estado de sintonia que corresponde a um tecido alvo e um segundo estado de sintonia que corresponde a um tecido de fundo. O sistema pode estar configurado para gravar imagens nos diferentes estados de sintonia e gerar uma imagem de pontuação que corresponde ao tecido alvo com base nas imagens gravadas.
