Optical device and manufacturing method thereof

An optical device (300, 400, 500, 600, 700, 800) is disclosed that includes a plurality of radiation emitting elements (310, 410, 510, 610, 650, 710, 810) disposed on a substrate (305, 405, 705, 805) and a microlens (325, 425, 525, 625, 725, 825) disposed on the substrate such that a beam of radiation (315, 415) emitted by each of the plurality of radiation emitting elements propagates through the microlens. A method of manufacturing the optical device, and a time-of-flight sensor (1005) implementing the optical device are also disclosed. 公开了一种光学器件(300、400、500、600、700、800)，该光学器件包括设置在基板(305、405、705、805)上的多个辐射发射元件(310、410、510、610、650、710、810)和设置在该基板上的微透镜(325、425、525、625、725、825)，使得由多个辐射发射元件中的每个辐射发射元件发射的辐射光束(315、415)穿过微透镜传播。还公开了一种制造该光学器件的方法，以及一种实现该光学器件的飞行时间传感器(1005)。
