Abstract
Embodiments of the disclosure provide an optical sensing system for two-dimensional (2D) environmental sensing and an optical sensing method for the optical sensing system. The optical sensing system includes a rotary base and a one-dimensional (1D) optical sensing apparatus supported by the rotary base. The 1D optical sensing apparatus includes an optical source configured to emit optical signals, a 1D MEMS scanner configured to direct the optical signals towards an environment surrounding the optical sensing system, and a receiver configured to receive at least a portion of the optical signals reflected from the environment. The rotary base is configured to drive the 1D optical sensing apparatus to rotate around a first axis to scan the optical signals in a first dimension and the 1D MEMS scanner is configured to independently rotate around a second axis to scan the optical signals in a second dimension in the 2D environmental sensing.
