The research work described in these original papers was carried out at the Electronics Laboratory, Department of Electrical Engineering, and Infotech Oulu, University of Oulu, Finland, during the years 1994–2002, in projects funded by the Academy of Finland, TEKES and several industrial companies. The projects were headed by Prof. Juha Kostamovaara, who also supervised this work.
Papers I to III describe receiver channel electronics for a pulsed TOF laser radar. The research described in paper I was done jointly by the author and T. Ruotsalainen, who prepared the manuscript, and that in paper II by the author, T. Ruotsalainen and T. Peltola, who prepared the manuscript. The circuit was developed during the research and has since been processed several times, the latest version being designed by the author.
Papers IV to VI describe pulsed TOF laser rangefinding devices. K. Määttä designed the PCB and the software for the controller of devices reported in papers V and VI and assisted in the measurements.
Paper VII describes photodiodes integrable in standard silicon technology. The work was done jointly by the author and T. Ruotsalainen.
Papers VIII and IX describe receivers for pulsed TOF laser radar devices in which integrated photodiodes are used. The three-channel time-to-digital converter was copied from a circuit designed by A. Mäntyniemi and then modified by the author so that it can measure three stop signals instead of one.
