Latest Patents

Rolo holds a notable patent for a "Reading device and method for measuring energy and flight time using silicon photomultipliers." This invention introduces a readout apparatus that measures both time-of-flight and energy through the clever use of silicon photomultipliers (SiPM) coupled to a scintillator. This technology achieves timing measurements with an impressive accuracy of 50 picoseconds or lower upon calibration. The energy is calculated using a time-over-threshold technique, demonstrating performance only limited by scintillation statistics. To maximize efficiency, Rolo's design allows for a low power consumption of 10 mW per channel and employs a low impedance input amplifier alongside analog time-to-digital converters. The system can be triggered by a single photoelectron, boasting a signal-to-noise ratio exceeding 20 dB. This adaptable readout circuit works seamlessly with SiPMs featuring varying gains, polarities, and matrix sizes. Ultimately, Rolo's preferred model involves a multi-channel application-specific integrated circuit (ASIC) designed to handle 64 channels, setting a new standard in the field.
