To address the challenge of non-contact signal transmission for high-speed rotating components in aero-engines, a wireless laser communication system for rotating environments was designed. The system employs a vertical-cavity surface-emitting laser（VCSEL）and a PIN photodiode to establish an optical communication link. A field-programmable gate array（FPGA）master control module coordinates the MAX3656 driver chip and MAX3760/MAX3762 amplifier circuits to achieve efficient electrical/optical/electrical signal conversion and processing. Combined with self-developed host computer software, real-time data parsing and display are accomplished. Experimental results demonstrate that the system achieves stable data transmission at 100 Mb/s over a 20 cm distance, with a power consumption of only 3.45 W. No waveform distortion occurs when the input signal frequency is ≤100 MHz, and zero bit errors are observed in host computer data parsing.
