field, homogeneous far-field profile and emission perpendicular to the chip. The parameters of the grating coupler are numerically optimised to maximise simulated performances in the near infrared. The beam separation ratio can also be adjusted with the grating coupler efficiency to gather the two optical functions in one component, which is not possible with bulk optics. Another technology, called finite coherent ranging, integrates the entire Lidar system, including lasers, amplifiers and detectors, on a single chip. This design uses what is called a monostatic technique, where transmitting and receiving happen from the same pixel. This reduces manufacturing complexity significantly, eliminating the need for precise calibration and allowing for streamlined, large-scale production. This provides a configurable FoV of up to 100° x 40° with a 0.02° accuracy, both horizontally and vertically, and a range of up to 600 m, which is significant with a frame rate of 5-30 FPS. The system can also detect the velocity of a moving object with an accuracy of 0.05 kph (10 mm/s). All of this highlights the focus on how FMCW can be used in more integrated devices to reduce the size and power consumption of Lidar sensors. Underwater scanning Lidar can even be used underwater. The latest patents use scanning techniques to monitor the water temperature around human-made and natural structures. A single sensor can create a 3D image and a 3D water temperature map of the area at the same time. The latter can be used to monitor the temperature at the top of a well plug or internal pipe-sealing plug, for example, as part of an abandonment operation, during reservoir stimulation/ carbon reinjection or during reservoir lifting operations.
