摘要
采用数字频率合成器驱动声光可调滤光器(AOTF)实现红外单色光调谐控制系统,解决了AOTF波长连续、快速扫描的问题。对系统硬件组成做了详细说明,设计了系统性能测试实验。实验结果表明:波长分辨率为15．6～73．1nm,准确性优于2．0nm,重复性优于2．5nm。所得结果为非同向AOTF的应用提供了理论依据。
The digital frequency synthesizer technology was used to drive AOTF to realize infrared single light control system. Rapid continuous wavelength scanning was resolved. The hardware compositions of the system were described in detail. The system function experiments were designed. Experimental results showed that the wavelength resolution varies from 15.6 nm to 73.1 nm. Wavelength accuracy is superior to 2.0 nm and wavelength repetitiveness was superior to 2.5 nm. The results are valuable in the application of noncollinear AOTF.
