The design and experimental method for the use of a novel instrument for lightfastness measurements on artwork is
presented. The new microfadometer design offers increased durability and portability over the previous, published
design, broadening the scope of locations at which data can be acquired. This reduces the need for art handling or
transportation in order to gain evidence-based risk assessments for the display of light-sensitive artworks. The
instrument focuses a stabilized high powered xenon lamp to a spot 0.25 millimeters (FWHM) while simultaneously
monitoring color change. This makes it possible to identify pigments and determine the lightfastness of materials
effectively and non-destructively. With 2.59mW or 0.82 lumens (1.7 x107 lux for a 0.25mm focused spot) the instrument
is capable of fading Blue Wool 1 to a measured 11 ΔEab value (using CIE standard illuminant D65) in 15 minutes. The temperature increase created by focused radiation was measured to be 3 to 4°C above room temperature. The system was
stable within 0.12 ΔEab over 1 hour and 0.31 ΔEab over 7 hours. A safety evaluation of the technique is discussed which
concludes that some caution should be employed when fading smooth, uniform areas of artworks. The instrument can
also incorporate a linear variable filter. This enables the researcher to identify the active wavebands that cause certain
degradation reactions and determine the degree of wavelength dependence of fading. Some preliminary results of fading
experiments on Prussian blue samples from the paint box of J. M. W Turner (1755-1851) are presented.
Laser-based remote wind systems work from Doppler-shifted scattering by aerosols in the atmosphere. These devices have been developed over decades, but their integrated opto-components and the associated signal processing are only now reaching an operational state, thanks to new laser and detection systems emerging from the communication industry, where they are becoming stable, eye-safe, cost-effective, and commercial available. A fiber based laser Doppler anemometer (LDA) was developed in the laboratory. Measurements of moving hard targets (wheels, loudspeakers) and soft targets (spray) were carried out and will be reported upon. At the beginning of the development a virtual instrument was used to design the sensor and was subsequently modified after the first flight test using a CO2 LDA. It was used to design a compact fiber sensor.
