Abstract
- We demonstrate coded excitation of broadband terahertz for imaging applications. The encoded transmitter uses optical rectification of femtosecond laser pulses in poled lithium niobate patterned with a 53-bit binary phase code. The terahertz wave forms are detected by electro-optic sampling in zinc telluride. A digital pulse compression filter decodes the binary wave forms, producing broadband pulses at 1.0 THz. A two-dimensional imaging experiment shows comparable performance between the encoded transmitter and a zinc telluride emitter. [ABSTRACT FROM AUTHOR]
