“…By measuring the parameters of the secondary signal, the time of the event can be measured very precisely even without an ultra-fast ADC. The initial work reported an error of 10-20 ps [8] for single-shot measurements; this error was reduced to <5 ps in subsequent models of Event Timers [1,9].…”

“…The EET technology is used in the previous-generation Event Timers, such as A033-ET and A040-ET [1,9], which are installed in a large number of the world's SLR stations at the time of writing this manuscript (https://eventechsite.com/en/applications/, accessed on 7 July 2023). The accuracy of our existing Event Timers is comparable with the best industry analogues, such as GuideTech's GT668PCI-1 (https://www.guidetech.com/gt668pci-1/, accessed on 7 July 2023) (2 ps single-shot resolution) and research prototypes such as the work by Panek et al [10].…”

Riga Event Timers have the ability to measure the interval between events with high resolution, on the order of picoseconds. However, they have several drawbacks, such as sensitivity to environmental temperature changes and an inability to capture the amplitude of the events. In this work, we present the ETAM: a next generation Event Timer. Its innovative features include adaptive correction of measurement errors based on an internal temperature sensor, and integrated peak-detector circuit to determine the amplitude of nanosecond-duration pulses. Evaluation shows that the ETAM has high thermal stability with a root mean square error (RMSE) of <3 ps in a temperature range between 0 and +40 °C, and accurate event amplitude measurement capability, with <2.3 mV RMSE in the 100–1000 mV range. These improvements allow the ETAM to be used in satellite laser ranging, optical time-domain reflectometry, and other field applications that require temperature- and amplitude-based time correction in addition to high robustness, performance, and stability.

“…Standard clock phase fluctuations and long-term frequency instability depend on the type of oscillator and the environmental factors such as: temperature, vibration, supply voltage fluctuation, and noise [18,19]. In the special case of the equipment described in this paper, as long interval random pulses may be examined, long term accumulated JE should be taken into account.…”

An embedded time interval data acquisition system (DAS) is developed for zero power reactor (ZPR) noise experiments. The system is capable of measuring the correlation or probability distribution of a random process. The design is totally implemented on a single Field Programmable Gate Array (FPGA). The architecture is tested on different FPGA platforms with different speed grades and hardware resources. Generic experimental values for time resolution and inter-event dead time of the system are 2.22 ns and 6.67 ns respectively. The DAS can record around 48-bit × 790 kS/s utilizing its built-in fast memory. The system can measure very long time intervals due to its 48-bit timing structure design. As the architecture can work on a typical FPGA, this is a low cost experimental tool and needs little time to be established. In addition, revisions are easily possible through its reprogramming capability. The performance of the system is checked and verified experimentally.

Space debris is a major problem for all the nations that are currently active in space. Adopting high-precision measuring techniques will help produce a reliable and accurate catalog for space debris and collision avoidance. Laser ranging is a kind of real-time measuring technology with high precision for space debris observation. The first space-debris laser-ranging experiment in China was performed at the Shanghai Observatory in July 2008 with a ranging precision of about 60-80 cm. The experimental results showed that the return signals from the targets with a range of 900 km were quite strong, with a power of 40W (2J at 20 Hz) using a 10ns pulse width laser at 532 nm wavelength. The performance of the preliminary laser ranging system and the observed results in 2008 and 2010 are also introduced.
