Abstract

By shaping the output from 3THz QCL, Gaussian-distributed THz source with very small divergence was obtained. With this good-quality QCL source, a Terahertz in-line digital holography set was built up. Resolution of this Terahertz in-line digital holography set is as small as 200μm, which is the smallest resolution reported up to now.
