Claim Text:
1. A method for light detecting and ranging (LIDAR) measurement of a speed of a medium including air through which an aircraft is traveling, comprising: directing a laser pulse having a pulse duration at the medium; and operating a detector to perform a detecting operation during an exposure period to detect radiation that is within a spatial measurement range and is being subsequently emitted from the medium upon exposure to the laser pulse, the detecting operation including selecting the spatial measurement range having a magnitude such that the pulse duration is shorter than a time required for the laser pulse to pass through the spatial measurement range by operating the detector in a non-detecting state for a first time duration that begins at a time of emission of the laser pulse and in a detecting state for a second time duration that begins during the exposure period at the end of the non-detecting state, at least one of the first and second time durations being less than 500 μs.
