DEVICE TO FORM MULTI-IMAGE OF TERAHERTZ BAND AND VISIBLE LIGHT BAND

摘要

Since a new quantum-cascade semiconductor heterostructure laser generating an electromagnetic wave of 4.4 THz has been developed, Hz light source technology is applied widely to medical science, industrial fields, pollution investigation, security screening and the like, but a mono-pulse THz system is applied to TDS to be used for biomedical images. The present invention relates to a device to form a multi-image of a terahertz band and a visible light band, capable of synthesizing an image of a terahertz band and a visible light band by obtaining the image through a single optical system.;COPYRIGHT KIPO 2019
