A Superconductive High-Resolution Time-to-Digital Converter
نویسندگان
چکیده
We are developing an ultra-high resolution timeto-digital converter (TDC) based on a novel scheme combining a digital “coarse” TDC and analog “fine” TDC. The coarse TDC is derived from a previously reported RSFQ time digitizer based on binary counters. The fine TDC is based on an analog prescaler. A 31 GHz counter defines the coarse (~32 ps) time resolution, while the prescaler provides a fine time resolution by measuring time within a clock period with 4 ps resolution.

In this paper, we present a high accuracy laser range finder and velocimeter using ultra-fast time-to-digital converter (TDC). The system operation is based on the measuring the round-trip time of a narrow laser pulse. A low-dark current high-speed PIN photodiode is used to detect the triggered laser beam and to produce start signal. The pulsed laser diode generates 45W optical power at 30ns du...
