  • M. Niedźwiecki

  - MECHANICAL SYSTEMS AND SIGNAL PROCESSING - Rok 2014

  Conveyor belt type checkweighers are complex mechanical systems consisting of a weighing sensor (strain gauge load cell, electrodynamically compensated load cell), packages (of different shapes, made of different materials) and a transport system (motors, gears, rollers). Disturbances generated by the vibrating parts of such a system are reflected in the signal power spectra in a form of strong spectral peaks, located usually in...

  • P. Wierzba
  • A. Kwiatkowski

  - Rok 2011

  Selected problems of development of a portable Raman spectrometer having small size, reduced power consumption and robust construction are shown. The device dedicated for semiskilled personnel uses two lasers: 785nm and 355nm. Results of preliminary tests are presented. Also data processing procedures as well as problems referred to Raman signals acquisition through packages and influence of interfering signals are discussed.

  - Rok 2010

  The fast identification of explosives, narcotics and other chemicals carried on board of ships or transported in containers to the harbors is an important problem of maritime security. Raman spectroscopy is widely used for fast identification of various chemicals. Continuous progress in the field of photonics has resulted in commercial availability of low-power compact Raman spectrometers which can be integrated into portable systems....
