In this article,two terahertz transmission imaging systems are built with a 2.52 THz continuous wave laser and two types of sensors.One is array scanning system using a 124 124 pyro-electric array camera as the detector;the other is a point-wise scanning system utilizing a Golay cell as the detector.The imaging speed and quality is briefly analyzed.Terahertz(THz)imaging results demonstrate that the array scanning system has higher imaging speed with lower resolution.The point-wise scanning system has higher imaging quality with lower speed.
