    Understanding spectrally controlled interferometry

    Robert Smythe
    Revolutionary innovations are rare. In the field of optical test interferometry, the HeNe laser revolutionized its application and use; now, SCI promises to do the same.
    FIGURE 1. A card printed with 1 mm black/white line pairs oriented horizontally (a) and vertically (b) can be used to assess vertical and horizontal interferometer imaging performance, respectively. Image degradation is seen at the edges of the image in this Gen II interferometer, indicating limitations in spatial frequencies that can be measured.
