System and method for preforming simultaneous bilateral measurements on a subject in motion
First Claim
1. A system for performing simultaneous bilateral measurements on a subject in motion at a test location, comprising:
- a plurality of observable targets disposed at selected positions on the moving subject;
wavelength-specific first and second target observing means, disposed on opposite sides of said test location and facing the same, for imaging each other while observing those of said targets as are respectively observable; and
first and second lighting means, respectively cooperating with said first and second target observing means to enable selected observation thereby, for providing lighting at respective first and second wavelengths such that said first observing means observes only at substantially said first wavelength and said second observing means observes only at substantially said second wavelength.

Abstract
A system is provided for performing simultaneous bilateral measurements on a subject in motion at a test location. The system employs a plurality of observed targets attached to the moving subject, the targets being viewed simultaneously by each of two cameras disposed on opposite sides of the subject. Each of the cameras has associated therewith a light source emitting a light of a selected wavelength, the wavelengths for the two cameras being deliberately selected to be different enough to enable each camera to image the light source of the other without corruption of the observed data. The simultaneously operating two camera units may be computer controlled in preprogrammed manner or may be controlled by the operation of a manual control panel. In either case, the overall intensity of the two light sources providing illumination at the two selected different wavelengths facilitates the provision of illumination which avoids confusion by reflectance from the subject at other than the selected targets.

20. A system for bilateral, variable intensity, wavelength-discriminated, illumination for simultaneous bilateral observation of targets mounted to a moving subject, comprising:
-
first and second lighting means for providing first and second lighting at respective controlled intensities; and means for filtering light provided by said first and second lighting means at respective first and second wavelengths, to illuminate selected ones of said targets with said filtered lighting at one or the other of said first and second wavelengths to thereby enable wavelength-specific observations of light reflected from the targets. - View Dependent Claims (22)
