Optical Readout System for Bi-Material Terahertz Sensors
Abstract
The objective of this work is to design, assemble, and characterize an optical readout for bi-material MEMs sensor arrays that can be integrated into a THz imaging system. All this effort is a contribution to the goals of the research conducted by the Naval Postgraduate School Sensor Research Laboratory on designing and fabricating THz-optimized bi-material MEMs sensor arrays for THz imaging. Basic concepts of THz radiation and detection are presented. Several aspects of THz imaging, and sensor's array readout possibilities, are discussed in terms of the principle of operation for this type of sensor. An experimental optical readout was assembled during this research, and its configuration is shown, as well as all of its component details. The experimental setup was characterized following a method described in this work, and the obtained results are analyzed. Finally, one possibility of optical readout integration with a THz imaging system is suggested.
