- 10ns resolution
- Event-driven output
- USB 3.0
The NovoViz NV04ASC-HW Asynchronous photon-driven camera was developed for applications requiring high sensitivity and/or frame rate but with reduced output bandwidth.
The camera combines the benefits of a single-photon avalanche diode (SPAD) camera, namely the single-photon resolution and fast operating speeds, with the benefits of an event camera – low output data rates.
Our innovative sensor architecture streams photon events with nanosecond timestamp resolution and latency over a conventional, low cost USB interface. The camera is well suited for high dynamic range imaging, low light imaging, depth sensing, obstacle detection and visual odometry, among others. Due to the advanced architecture, the camera can operate at an equivalent frame rate of 100 million single-photon frames per second which comes with significant advantages over current solutions.
Applications
SPAD cameras for space observation
SPAD cameras are increasingly relevant in space missions due to their ability to detect extremely low photon fluxes, making them valuable for applications such as space-based imaging, optical communication, and scientific experiments requiring high sensitivity.
We have characterized a fligth version of the NV04ASC-HW camera during its operation in Low Earth Orbit (LEO). The primary objective was to verify whether the noise characteristics, specifically the dark count rate (DCR) and hot pixel percentage, remain stable throughout launch preparation and in-orbit operation.
