Abstract

The measurement accuracy of laser telemeters have been analyzed, taking into account the statistical properties of the propagation, detection, and measure process. For an arbitrary waveform of the light intensity modulation envelope, the optimum filter response and the resulting accuracy are found. As special cases, the optical radar and the sine wave modulation techniques have been considered, and their accuracy and optimum mode of operation are evaluated and discussed.

  13. Being h(t) = hf(t)*hd(t), a constraint is implied on the detector impulse response hd(t) such that the effective filter response hf(t) can be realized. Assuming an adequate speed of response for the detector, the distinction between h(t) and hf(t) can be overlooked.
