Design and Performance Test of Pulse X-Ray Receiver Based on LYSO-SiPM for X-Ray Communication

X-ray communication (XCOM) is a type of wireless optical communication technology that uses modulated X-ray beam as the carrier of data transmission. As a core component of an XCOM system, the X-ray signal receiver determines the upper limit of the communication rate and the quality of communication. A pulse X-ray signal receiver based on an LYSO-SiPM detector and a field-programmable gate array signal processing module is designed to solve the problems of considerable background noise and weak signal strength in the actual XCOM process. The low bit error rate (BER) at the Mbps rate is realized first for XCOM. An XCOM performance test system is used to test the receiver's signal output characteristics and communication performance. The communication rate reaches 1.21 Mbps with BER less than 1.0 × 10
⁻⁵
. The designed pulse X-ray signal receiver can effectively identify X-ray pulse under high bandwidth and weak signal receiving power.
