近年來隨著自動駕駛車的興起,促使先進駕駛輔助系統(ADAS)蓬勃發展,而光達即是扮演自動駕駛車眼睛的角色,具有測量距離遠及高精度空間解析度的能力。本研究著重於開發製程整合微透鏡之光達掃描平台,使用半導體製程製作MEMS致動器與光學相位陣列(OPA)光電元件相互整合,達到空間三維掃描的能力。相較於一般光學微平台,通常在製作透鏡時有組裝上的問題,此篇在製程間製作二相位Fresnel lens於掃描平台上,具有繞射聚焦及光束調控的效果,並透過彈簧設計及頻率控制將MEMS掃描平台制動於共振頻上,放大位移量輸出,使雷射光掃描時能有較大的範圍。
目前設計之元件在驅動電壓15V下,在同平面能有大於±20μm的位移量,而雷射光有±6.84°(f=100μm)及±2.29°(f=500μm)的偏轉角度。
With the rise of autonomous and electric vehicles, advanced driver assistance system (ADAS) is thriving. LiDAR is playing the role of the eyes, with the ability to measure distance and high-precision spatial resolution. This research focuses on the development of integrated micro-lenses for optical microscopy, and uses the semiconductor process and optical phase array (OPA) optoelectronic components to achieve the capability of 3D space scanning. Compared with the general optical micro-platform, usually in the production of lenses have the assembly issues. This article makes the Fresnel lens, with the diffraction focus and beam steering effect, on the scanning platform during process. Through the spring design and frequency control, this study operates the MEMS scanning platform on the resonance frequency to enlarge the displacement output so that the laser scanning can have a larger range.
Currently devices can have a displacement greater than ± 20 μm in in-plane direction at a driving voltage of 15 V, while 1550nm laser light has a deflection angle of ± 6.84° (f=100 μm) and ± 2.29° (f=500 μm).
