DIGITAL HETERODYNE TOPOGRAPHY (MOIRE, CONTOURING, PROFILOMETRY).BELL, BERNARD WHITE, JR. January 1985 (has links)
Digital heterodyne methods are employed in conjunction with periodic fringe projection to produce a fast automated surface relief measurement technique. A method of sampling the image with a solid state detector array which produces a moire fringe image free of the noise terms normally present with moire techniques is presented along with an extension to Whittaker-Shannon sampling theory to cover the moire aliasing phenomena. The limitations imposed on the surface slopes by the requirement that the properly moire sampled image spectra must be confined to a moire interval are given. Moire sampling allows an optical processing step (removal of the reference surface tilt), while classical nonaliased sampling produces the same information with respect to a tilted surface. General additive noise is analyzed as regards both integrating bucket and phase stepping algorithms and yields a signal to noise ratio dependent error with twice the frequency of the fringes for some algorithms. A phase averaging technique which eliminates these oscillatory errors as well as those caused by reference phase shift errors in all the algorithms is demonstrated. Both parallel and divergent geometries are discussed. The feasibility is experimentally demonstrated with results for the parallel case based on a system composed of commercially obtainable components.

Determination of crustal interface topography from potential fieldsPilkington, Mark. January 1985 (has links)
A method is presented for the determination of interface topography of multi-layered crustal models from gravity or magnetic data. The technique is developed within the framework of discrete linear inverse theory and exploits the quasi-linearity of the problem to derive a simple cost-effective algorithm suitable for use on large gridded data sets. / Variation of auxiliary parameters allows a suite of acceptable models to be produced rapidly and appraised in the light of available geological and geophysical evidence. When independent knowledge concerning the behaviour of specified interfaces is available, the incorporation of such data in the form of linear equality constraints is outlined. / The proposed method is applied to Curie isotherm and Moho mapping in the Abitibi greenstone belt.

Topographical analysis of reinforcement produced variability: Generalizations across settings and contingencies.Gomez, Francisco 08 1900 (has links)
This study evaluated the effects of programming a variability contingency on one object and the generalization of variability across other objects and contingencies when the defining features of the variable responses were topographical differences. A dog's interactions with five different objects were measured under both ANY (where any physical contact with the object would be reinforced on a fixed ratio schedule) and the VAR contingencies (where only the novel responses per trial would be reinforced). The ANY contingency produced stereotyped responding of behavior with all objects. When one of the dog-object interactions was changed to the VAR contingency, a marked decrease in stereotypic behavior and an increase in novel responses in the form of topographical combinations were observed across both contingencies.
