Single-Photon Detection Bridges the Gap Between Quantum Tech and Industrial Users
The article covers the following companies and startups:
- NovoViz: Integrating SPAD sensors with on-chip digital processing for industrial applications.
- VTEC Lasers & Sensors: Offering "Quspads" InP-based SPAD chips with high efficiency and room-temperature operation.
- Ubicept: Software platforms for real-time reconstruction with megapixel color SPAD sensors.
- Photon Force: High-throughput SPAD array camera with 50-picosecond temporal resolution.
- Quantum Computing Inc. (QCi): Quantum lidar and quantum photonic vibrometer systems.
- ID Quantique (IDQ): SNSPD systems for integrated circuit inspection and Ariane 6 rocket monitoring.
- Sony: Manufacturer of SPAD-based lidar modules.
The Photonics article's author ignores CMOS quanta image sensors, demonstrated years ago at the 160+Mpixel level by Gigajot Technology, Inc. Granted those sensors don't have the nsec photon arrival timing of SPADs, but in terms of pixel resolution, low power, and high photon number resolution, CMOS QIS was already far ahead of today's SPADs.

ReplyDeleteCan I buy it?
DeleteThe Photonics article also ignores VoxelSensors contribution to novel SPAD imagers with their SPAES architecure.
ReplyDeleteProbably because almost 0 technical info on site.
