The pulsed time-of-flight laser range finding techniques based on a laser diode transmitter have shown great potential in industrial distance measurement applications such as the measurement of level heights in silos, positioning of tools and vehicles, velocity measurement, anti-collision radars and in proximity sensors, for example, giving a mm-level accuracy even to non-cooperative targets in a range of tens of meters. The usability of technology could be further enhanced if the laser radar could be realized as an integrated micro-module giving advantage in power consumption, size and price. The necessity for this is the realization of the basic laser radar functions, the receiver and the time interval measurement unit, as high-performance integrated circuits. Inspired by this aim, the present article describes the realization and performance of two integrated time-to-digital converters based on analogue time-to-amplitude conversion and digital delay line interpolation techniques. These circuits are realized in BiCMOS and CMOS processes, respectively, and enable one to achieve a single shot precision of 20-30ps and picosecond level accuracy in a wide measurement range and varying operation conditions.

Impulsowe dalmierze laserowe są szeroko stosowane w wielu dziedzinach przemysłu, np. w geodezji i badaniach naukowych. Artykuł zawiera opisy projektów i wyniki testów dwóch scalonych konwertorów czasowo-cyfrowych opracowanych dla takich zastosowań. Pierwszy z nich wykorzystuje metodę przetwarzania czas/amplituda/liczba, a drugi metodę interpolacji z cyfrowymi liniami opóźniającymi. Układy te zostały zrealizowane jako scalone (ASIC) w technologii odpowiednio BiCMOS i CMOS. Uzyskano standardową niepewność pomiarową w zakresie 20-30 ps i wysoką stabilność w szerokim zakresie pomiarowym i przy zmiennych warunkach pracy.
