The results of this research e ort demonstrate that the combination of two recent approaches improves the performance of adaptive optics in directed energy and laser communication scenarios. The rst approach is adaptive control, which o ers improved performance over xed-gain controllers in the presence of rapidly changing turbulence. The second approach incorporated into the study is a dual-mirror system. The two mirrors are a high-bandwidth, low-actuator-stroke (tweeter) mirror and a low-bandwidth, large-actuator-stroke (woofer) mirror. The woofer-tweeter combination allows for better compensation of the large-variance, high-spatial-frequency phase distortion generated by strong turbulence. Two di erent adaptive controllers are presented.\u003c\/p\u003e","brand":"Mia Karts","offers":[{"title":"Default Title","offer_id":51961385025824,"sku":"NEW1288368739","price":69.54,"currency_code":"USD","in_stock":true}],"url":"https:\/\/miakarts.com\/products\/adaptive-control-of-woofer-tweeter-adaptive-optics-1288368739","provider":"Miakarts Books","version":"1.0","type":"link"}
