Abstract

A FIBEL-OPTIC MODULE FOR BROADBAND SCATTERING MEASUREMENTS WITH ROD LENSES AND CCD PHOTODIODE MATRIX IN THE VISIBLE REGION

Petar Petrov and Vanya Plachkova*

ABSTRACT

A fiber optic module using radially arranged rod lenses for the measurement of broadband scattering was designed. Precise centering of the module was performed. The error deviation and signal interference is reduced to fit in the norms of tolerance. Each rod lens module covers several pixels of the CCD photodiode matrix using an optical fiber. Seven lenses which enter into the structure of the unit register from seven different angles the scattering from the sample. This enables a fast analysis of liquid samples. Fiber optic module with rod lenses can be used for the analysis of scattering spectra of various liquid samples in the food industry. The effect of scattering in different brands of fruit juices was examined. It is shown that the module has been successfully used for the needs of the food industry for analysis of liquid samples. The fiber optic module with rod lenses performs fast test of samples for impurities that get detected by the scattering effects in liquid natural food products.
