Cameras

The multispectral camera is used to capture high resolution, high dynamic range, multispectral images. The camera system uses commercial products to the greatest extent and is based on a Sinar 54H studio camera. The 22 mega pixel Kodak KAF 22000CE sensor used within the digital back provides enough resolution to print medium sized images (e.g. 400mm x 500mm, 260ppi). The camera back has micro-positioning capabilities; the sensor is moved four times to position each color of the Bayer patterned CFA over every pixel's spatial location. Therefore, demosaicing is not necessary. Additionally, active direct thermoelectric cooling of the sensor reduces thermal noise and increases the signal-to-noise ratio in dark image areas which is important for HDR scenes. The only modifications of the commercial system is the replacement of the IR-cutoff-filter by a transparent glass filter and use of colorimetrically and spectrally optimized blue and yellow filters in front of the lens. These filters are included in a custom made filter wheel. For vibration-less acquisition the camera is sitting on a studio camera stand (AROBO DSS-OMEGA). The system is adapted from a very similar system developed by the Munsell Color Science Laboratory (RIT) for multispectral art work capturing.

The BYK micro-TRI-gloss is a gloss measuring device with three geometric configurations of light source and detector. From one of the standardized angles counted to the perpendicular, light falls on the sample. The glossy to matte surface reflects the incident light more or less specular. For each of the three measuring geometries, the directionally reflected light is detected in gloss direction. The quotient of reflected and incident light is a measure for the gloss of the considered surface.
