<p>Methods and apparatus are presented for distance measurement using laser pulses in which at least one of an attenuation function and an offset of the attenuation function relative to the send pulse is variable to accommodate differing measurement needs. In some embodiments, at least one of an attenuation function and an offset of the attenuation function is fixed relative to the send pulse for some number of measurement cycles and information derived from the result is used to modify either or both of the attenuation function and offset of the attenuation function relative to the send pulse for subsequent measurement.</p> |
