A system for determining airborne light detection and ranging (lidar) installation angles includes an airborne platform, a light detection and ranging (lidar) apparatus, a navigation system and a processor. The airborne platform performs a calibration flight in an orbit. The lidar apparatus is installed on the airborne platform for wind-velocity measurement. The navigation system is on board the airborne platform and measures motion data associated with movements of the airborne platform and generates a navigation signal. The processor determines in real time one or more installation angles of the lidar apparatus on the airborne platform to improve accuracy of the wind-velocity measurement.

Aspects of the invention generally relate to illumination gas imaging and detection. Camera systems can illuminate a target scene with light sources configured to emit absorbing and non-absorbing wavelengths with respect to a target gas. An image of the target scene illuminated with a non-absorbing wavelength can be compared to a non-illuminated image of the target scene in order to determine information about the background of the target scene. If sufficient light of the non-absorbing wavelength is scattered by the scene toward a detector, the target scene comprises an adequate background for performing a gas imaging process. A camera system can alert a user of portions of the target scene suitable or unsuitable for performing a gas imaging process. If necessary, the user can reposition the system until sufficient portions of the target scene are recognized as suitable for performing the gas imaging process.
