cronologic products applications
TOF mass spectrometry
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.
Time-Correlated Single Photon Counting
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.
low energy nuclear physics
While many aspects of nuclear physics are considered well understood after almost 100 years of research, several challenging questions are still open and under investigation. Our TDCs are used in gas detectors for nuclear physics experiments helping to understand the microcosm of the nucleus.
fluorescence lifetime correlation spectroscopy
Fluorescence-correlation-spectroscopy is a highly sensitive optical measurement method. Fluctuations in the fluorescence emission intensity over time are recorded, which are caused by individual fluorophores that pass through the detection volume.
The decay time of an 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.
Quantum phenomena such as superposition, uncertainty, and entanglement are studied in quantum research with the goal that they can be safely fabricated when needed and made useful in various disciplines.
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.
Time Domain Reflectometry
TDR (Time Domain Reflectometry) is an electronic measurement method that measures reflections along a conductor. It belongs to the category of Distance-to-Fault (DTF) measurements. TDR measurements provide meaningful information about the broadband behavior of transmission systems.
In optical time-domain reflectometry the time of the reflections is determined from the reflection loss by measuring from the same end of the fiber how much light returns via the Rayleigh backscatter or is being reflected from individual locations along the fiber.
The currently most advanced spectral imaging technique is based on single photon-counting detectors. Such detectors typically require precise timing measurements and corresponding applications strongly benefit from fast data acquisition electronics.
phase shift measurements
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.
Neutron detectors are not only used in the in area of radiation safety, e.g. in reactor instrumentation or special nuclear material (SNM) detection. They are as well employed in fusion plasma physics, particle physics, materials science, and even cosmic ray detection.
