A diode laser and Raman sensor system for in situ quality control

Bernd Sumpf, Heinar Schmidt, Martin Maiwald, and Heinz-Detlef Kronfeldt

At a time when food prices are soaring and tales of contamination make headlines, consumers expect not only value for their food dollars, but assurances that what they buy is fit to eat. These concerns raise questions of quality control up and down the food-production chain. Unfortunately, determining food quality has often been based on experts’ empirical knowledge or on time-consuming and expensive laboratory analytical methods. Currently parameters monitored and documented on-line are limited. Temperature and time, for instance, are a few that can be recorded with (radio frequency...Read full article

    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
