| Abstract: | The theory of time to amplitude conversion (TAC) method and its application in laser range finding system are presented The experiment results of a time to amplitude converter are given and various effects in linearity are discussed The accuracy and resolution of the TAC are tens of picoseconds and less than ten picoseconds, respectively By utilizing time to amplitude method, the accuracy and resolution of traditional laser range finding system can be improved from the order of 100mm to the order of 10mm and the order of 1mm, respectively |
