The proposed compact terahertz focal plane array technology would enable significant progress toward making a high sensitivity, low cost THz imaging system. Deployment of these newly developed detector devices would result in successful implementation of important applications in scientific R&D, biomedical, non-destructive testing, molecular spectroscopy, defense and security imaging, semiconductor device testing, and communications. Thz radiation is non-ionizing and non-destructive, which makes it ideal for probing structural and material defects in airframes or bridges, such as from manufacturing or fatigue factors. It is also ideal for biomedical diagnostics, such as cancer screening. Regular high sensitivity diagnostic screening of cancer is of high clinical importance for repeated assessments, patient monitoring and follow-up. Cancer is rapidly advancing as the second leading cause of death. Common examples are stomach cancer and colon cancer. High accuracy and resolution THz imaging would be an invaluable tool in early detection and monitoring of these and other types of cancers. The development of the proposed technology would also be able to satisfy an unmet medical need to accurately image the cornea. Providing this diagnostic capability is of clinical importance. End stage endothelial dysfunction results in corneal transplantation. Nearly 30,000 corneal transplants were performed in the U.S. alone in 2014 for endothelial dysfunction. Dry eyes are a common affliction and represent a $3.5 billion market of diagnostics and treatments (many elective) globally. Inflammation of the cornea, i.e. keratitis, results in nearly a million clinic or ER visits a year with direct health expenditures costing an estimated $175 million. Reducing need for corneal transplantations reduces patient morbidities and potential cost savings of up to $10,000-$15,000 per transplant.
