Optical Observations of Blazars: the Perugia Monitoring [PDF]
Mem.Soc.Ast.It. 73 (2003) 1024, 2002 In eight years, during the blazar monitoring program performed with the Perugia automatic telescope, we were able to collect about 20000 $BVR_cI_c$ photometric points, contributing to get knowledge on the optical flux history of many sources brighter than magnitude $V=17.0$. This intensive and constant optical monitoring is essential to perform studies

ContactLess Integrated Photonic Probe for light monitoring in InP-based devices [PDF]
arXiv, 2014 The increasing complexity of photonic integrated circuits requires the possibility to monitor the state of the circuit in order to stabilize the working point against environmental fluctuations or to perform reliable reconfiguration procedures. Although InP technologies can naturally integrate high-quality photodiodes, their use as tap monitors ...

Long-term stability of fibre-optic transmission for multi-object spectroscopy [PDF]
, 2012 We present an analysis of the long-term stability of fibre-optic transmission properties for fibre optics in astronomy. Data from six years of operation of the AAOmega multi-object spectrograph at the Anglo-Australian Telescope is presented. We find no evidence for significant degradation in the bulk transmission properties of the 38 m optical fibre ...
