The hot electron bolometer and heterodyne receiver technology to be developed will have direct relevance to NASA Earth observing programs. Besides SOFIA, there are also several other NASA instrumental programs for which our THz sensor will be useful. The range of targeted planets includes Mars, Venus, Jovian and Saturnian systems. Development of the mixer for 2-5 THz will stimulate new goals in future planetary investigations. The market opportunity for terahertz based applications includes industrial and environmental monitoring, medical diagnostics, medical imaging, medical therapeutics, drug development and security. Esensors will initially pursue security applications, and airport security screening because of funding in the area. The Transportation Security Administration (TSA) has been tasked with implementing 100% inspection of air cargo on passenger planes and is backed by a $250M in funding. Esensors expects to sell the THz receiver at an estimated price of $15K. We estimate the total market to be in the range of 2400 systems.
