Extended Data Fig. 5: FMCW LiDAR set-up.
From: Ultrafast tunable lasers using lithium niobate integrated photonics
(a) The photo of the set-up for coherent optical ranging experiment containing the target - a polystyrene doughnut mounted on the stage and an instrument box wall behind, and the scanning pattern of the galvo-mirrors. (b,c) The voltage signal profiles applied to two galvo-mirrors enabling two angular degrees of freedom - ϕ and θ - for scanning, and their fits with a perfect triangular ramp. (d) The actual data of the scanning pattern and its reconstruction after fitting the angular coordinates.
