Naturforsch. 44a, 1219 1225 (1989); received October 21, 1989 We present a new laser tandem mass spectrometry technique in a reflectron time of flight (TOF) instrument. A first pulsed laser performs the multiphoton ionization and the primary photodissoci- ation. A newly designed ion source permits a high mass resolution in the space focus of the 12 cm long first linear TOF, where then the

Introduction The mechanical properties of structural timber can be assessed by acoustic wave measurements. The method is mainly applied for predicting the modulus of elasticity (MOE) of wood through time-of-flight (ToF) acoustic wave determination in the longitudinal direction (ToF long ), which is influenced by moisture content (MC), temperature, dimension of the timber, test procedures and the instruments applied ( James 1961 ; Gerhards 1982a ; Bucur and Böhnke 1994 ; Wang 2013 ; Íñiguez-González et al. 2015 ).

1 Introduction Optical time domain reflectometers (OTDRs) are widely used in optical fiber network installation as a diagnostic tool. They are used to detect fault locations and measure loss along the optical fiber link [ 1 ]. An OTDR measures the length of an optical fiber by measuring the time of flight (TOF) of a modulated laser signal. In order to calibrate an OTDR, a more accurate system is required. Moreover, the measurement should be traceable to the SI unit of time, the second, and hence the SI unit of length, the meter, from definition of meter
