Frame-based streaming data flows through a graph of multiple interconnected processing modules. According to the invention, the spectrometric measuring head with means for recalibration comprises a housing which is provided with a window and which contains an illumination source, a spectrometer arrangement and at least two standards for internal recalibration. The bundled fiber guide is coupled to the energy distribution tuner to receive a substantially uniform distribution of high power energy. Third metal plating layers are formed at the anode and the cathode portions to obtain a capacitor element. A plurality of the compressed data rows are restored in sequence at a high speed so as to reduce the time required for the restoration. According to the invention, when the chamber fills with fluid, the glazed structure darkens and, when the chamber empties, the structure becomes transparent once again.
