Automating Knife-Edge Method Of Thz Beam Characterization, Christopher Charles Faber
Undergraduate Research & Mentoring Program
The goal of this project is to create a time and cost-effective solution for THz beam profiling.
The knife edge method of beam characterization is a technique to verify the intensity profile of a beam involving traveling a blade orthogonal to the beam path and measuring transmission in successive steps. We use a vector network analyzer (VNA) to measure S21 transmission from a THz source. Manual implementation of this method was time-consuming and inefficient.
Project hardware includes an Arduino, a motor shield, and a ball screw linear rail with stepper motor actuator. Software was created in LabView and data is …
