Based on recent discoveries, we introduce a method to project a single structured pattern onto an object and then reconstruct the three-dimensional range from the distortions in the reflected and captured image. Traditional structured light methods require several different patterns to recover the depth, without ambiguity or albedo sensitivity, and are(More)
Prolonged exposure to weightlessness is known to produce a variety of cardiovascular changes, some of which may influence the astronaut's performance during a mission. In order to find a reliable indicator of cardiovascular adaptation to weightlessness, we analyzed data from nine male subjects after a 24-hour period of normal activity and after a period of(More)
The scalar field model is a complex exponential. It does not include E and B fields or polarization. But it works quite well for coherent light holography and acoustic imaging. Other references for use of this model are Fourier optics, [1] diffraction optics, holography, array signal processing[2-4] and acoustic imaging. The field equation is () ⎟ ⎠ ⎞ ⎜ ⎝ ⎛(More)
