  • Optical distance measurement
    Patent number: 6753950
    Abstract: Optical distance equipment transmits an optical signal and determines distance by locating the peak of a correlation with the reflected signal. The number of calculations required for the correlation is greatly reduced by using a combination of a coarse and fine correlation. The accuracy of the distance measurement is also improved by calculating the point of intersection of two best fit lines to either side of the correlation peak. The signal is preferably modulated by a maximum length sequence.

  • Multi position alignment system
    Publication number: 20030002034
    Abstract: An alignment system for determining the alignment of a plurality of components has a plurality of targets (2), one target being associated with each component. An optical arrangement (4, 1) is associated with each target, for selectively providing an image of the associated target within the field of view of an optical viewing device. This arrangement enables the image of a single target to be in the line of sight of a viewing device (for example telescope), so that the depth can be determined unambiguously.
