Optical inspection of industrial materials by unidimensional Fourier transform


, : Optical inspection of industrial materials by unidimensional Fourier transform. Applied Optics 27(22): 4645-4652

Optical techniques are appropriate to industrial inspection tasks because of their noncontact nature, high response speed, and increasing ruggedness and affordability. This paper relates to the development of two electrooptical systems for the inspection of woven webs and of extruded wires. In both cases, parameters of industrial interest are inferred from the light beam distribution after interaction with the material under analysis. Suitable optical configurations provide a laminar light beam which is line array scanned and Fourier transform processed. The emphasis is on the maximization of the measurement reliability, depth of field, and processing speed according to on-line application requirements.

Bovine tracheal gland (BTG) cells in culture show an epithelial-fibroblastoid transition after several passages. To investigate BTG cell phenotype changes, we studied the effects of both the culture medium and passage number on the expression of e...
