Paper Abstract

In recent years the use of opto-chemical sensors has grown in very diverse fields, particularly in environmental control. Luminescence methods are being developed because they entail some advantages. Two multi-parametric measurement system of low light intensity based on a CCD are evaluated in this article. The light arrives through several optic fibers from the corresponding sample or chemical sensor phase, where the luminous phenomenon is produced. Possible applications of this system include fields like environmental control, biology or medicine. Two low-cost CCDs have been used with the aim of evaluating their performance in situations of low luminosity so as to justify their possible use in measurement of luminescence phenomena. Both systems are made up, firstly of a CCD sensor and an analogical state, where the signal is amplified and suitably sampled. The whole system is managed by the control stage, made up of a programmable logic device, so as to achieve flexibility and integration.
