Cronologic presents an exciting series of low-cost, mid-resolution time-to-digital converters. The boards feature 500ps to 1ns single-shot resolution at a high readout bandwidth.
Time Taggers are ideally suitable in applications that do not require the highest single-shot timing resolution, but high data acquisition rates and the lowest multiple hit deadtime. These include certain types of mass spectroscopy (TOF-MS), time-correlated single photon counting (TCSPC) and frequency counting applications.
The TimeTagger4-1G features a bin size of 1 ns. The TimeTagger4-2G provides a bin size of 500 ps.
The decay time of an electronically excited fluorophore is typically in the range of a few nanoseconds. In fluorescence lifetime imaging the exponential decay of a sample is determined requiring a timing resolution in the picosecond regime. Our sophisticated TDC and ADC solutions master this job with excellence.
LIDAR Systems emit ultraviolet, visible, or near-infrared light to image objects and measuring the time-of-flight (TOF) of reflected photons. Such systems are used for object detection and tracking in many different fields, ranging from archaeology to agriculture, autonomous vehicles, and robots, etc. The high timing resolution of cronologic ADCs and TDCs is a key to reaching the highest ranging accuracy and our devices’ high data throughput allows for targeting even complex measurement scenarios.
In many TOFMS units, cronologic TDCs are used to measure precisely the arrival of single ions. From the arrival time, the ion’s time-of-flight is deduced, from which the mass-to-charge ratio of the detected particle can be determined. A crucial factor for a successful measurement is the extremely low cycle-to-cycle jitter of our TDCs and their very low multiple hit detection dead time.
In phase measurements, the phase of an incident signal is compared to the phase of a device's response signal. With increasing frequency, such phase shift measurements become more challenging. cronologic TDCs provide many features which help to address this difficult task.
Whether in astrophysics, materials science, quantum information science, quantum encryption, medical imaging, DNA sequencing, or in fiber-optic communication: Single-photon detectors (SPD) provide a timing signal from which, for example, fluorescence lifetimes of excited matter can be deduced (FLIM). This is the perfect job for our TDCs and in some applications already our "entry-level"-device can be employed.
Quantum key distribution (QKD) enables the tap-proof encryption of data by exploiting the quantum properties of light. For transmission of encrypted data single-photon sources (SPS) can be used for optimal performance. Our fast TDCs facilitate the development of single-photon counting receiver modules which convert single-photon detection events into streams of time-tags - synchronized to the excitation-laser source.
