摘　　要：光源控制技术是光纤陀螺技术研究领域的关键技术之一。为进一步提高光源的控制精度,从SLD光源驱动原理出发,提出光源模拟控制与数字控制方案,分析了电路原理,结合实际研究情况,从恒流精度、温控精度及光功率等关键技术指标出发,对两种方案进行比较并给出结论。Source control technology is one of the key research areas of FOG. To further improve the accuracy of source control, starting from the SLD light source driving principle, analysis of the circuit, source analog control and digital control scheme are proposed. Combined with the actual research situation, from the constant current accuracy, temperature control precision, optical power and other key technical indicators starting, the two options are compared and conclusions are given.
