SPADit

SPADit is a software tool designed for analyzing and visualizing single-photon avalanche diode (SPAD) sensor data. SPADs are a type of photodetector that can detect individual photons, making them useful in a variety of applications such as time-correlated single-photon counting (TCSPC), LiDAR, and quantum information processing. SPADit provides a user-friendly interface to process raw data generated by SPAD arrays or individual SPAD detectors.

The core functionalities of SPADit include data loading, filtering, and statistical analysis. It can handle various data formats commonly produced by SPAD readout electronics. Users can apply temporal and spatial filtering techniques to remove noise and isolate relevant signals. SPADit also offers tools for calculating key performance metrics of SPAD sensors, such as dark count rate, photon detection efficiency, and timing jitter.

Visualization is a significant aspect of SPADit. The software generates plots and heatmaps to represent the spatial distribution of photon counts, temporal photon arrival times, and other characteristics of the detected light. These visualizations aid researchers and engineers in understanding the behavior of SPAD devices and optimizing their performance for specific applications. SPADit aims to simplify the complex data analysis associated with SPAD technology, making it more accessible for researchers in photonics and related fields.
