Step distance measuring device based on femtosecond optical-frequency comb and measuring method thereof

InactiveCN102494615AAvoid mechanical movementEliminate measurement errorsUsing optical meansOptical pathPhysics
Disclosed are a step surface topography measuring device based on a femtosecond optical-frequency comb and a measuring method thereof. The measuring method includes steps of utilizing the femtosecond optical-frequency comb with repetition frequency and offset frequency which are locked to reach the microwave frequency reference as a light source; interfering measuring light with reference light, which is delayed by a certain light path, of split light beam; scanning repetition frequency of the femtosecond optical-frequency comb and acquiring positions of coherent peak value of light strength received by corresponding pixels of each step surface; and working out the absolute distance of steps according to the corresponding repletion frequency and light path delay of the coherent peak value. The measuring method overcomes the defects that light path is difficult to be regulated and precision is limited by motion precision of piezoelectric ceramic machinery when in use of the conventional measuring method, and has the advantages of high longitudinal resolution ratio and wide measuring range. Besides, the repetition frequency and offset frequency of the femtosecond optical-frequency comb are locked to reach the microwave frequency reference so that measuring results are traceable.
