In the paper you can find description around finding algorithm, the detector output, imaging sensor, signal, sensor, calibration, laser output, and vegetation. The paper presents explanation about instrument, algorithm, sampling, instrument performance, laser, laser altimeter, and topographic.
There are lots of information related to laser altimetry, pattern, oscillator, systems, range, photogrammetry, and output are described in this paper. Here are selected from the paper:
The receiver box can accommodate two more detectors, enabling Table 1 System characteristics of the LVIS altimeter Telescope aperture Telescope total FOV Detector FOV Detector band width Bandpass filter band width Digitiser sampling rate Digitiser effective bits Laser output energy Laser pulse width Laser spatial energy pattern Pulse repetition rate Žrep-rate. This includes the combination of the laser range data with GPS position and INS pointing information at the epoch of each laser shot and performing a series of transformations to rotate and translate the laser range from a local, aircraft reference system to a global reference system such as WGS-84.
Furthermore, the paper gives you information things like altimeter, design, the lvis sensor, system, digitisation, waveform digitisation, and waveform.
