Abstract

"MéTODO E DISPOSITIVO PARA AVALIAçãO DE SUPERFìCIE". A invenção refere-se a dispositivo e método para registrar as propriedades visuais de uma superfície, compreendendo um dispositivo de geração de imagens (3) para registrar a interação de luz (reflexão ou transmissão) com uma superfície, uma fonte de luz (2), e uma área de amostra para posicionar uma amostra (6) com uma superfície a ser examinada. O dispositivo de geração de imagens, a fonte de luz, e a área de amostra são dispostos de tal maneira que em uma imagem pelo menos uma das propriedades de superfície é registrada como uma função de uma variação contínua de ângulos entre a direção de iluminação (7,9) e a direção de observação (4,5). O dispositivo de geração de imagens é uma câmara de CCD. O dispositivo e método são adequados para gerar imagens e avaliar as propriedades visuais que são dependentes da geometria ótica, tal como comportamento flop e brilho."METHOD AND DEVICE FOR SURFACE EVALUATION". The invention relates to a device and method for recording the visual properties of a surface comprising an imaging device (3) for recording the interaction of light (reflection or transmission) with a surface, a light source (2). , and a sample area for positioning a sample (6) with a surface to be examined. The imaging device, light source, and sample area are arranged such that in an image at least one of the surface properties is recorded as a function of a continuous angle variation between the lighting direction ( 7,9) and the direction of observation (4,5). The imaging device is a CCD camera. The device and method are suitable for imaging and evaluating visual properties that are dependent on optical geometry, such as flop behavior and brightness.
