Advanced Photonix, Inc. Announces Entry into China Terahertz Research Market.

ANN ARBOR, Mich. -- Advanced Photonix, Inc. (AMEX:API) today announced that the Picometrix T-Ray[TM] 2000 has been chosen by Tsinghua University, Beijing, China, to be the focal point of their investigations into the applications of terahertz technology. Picometrix, an API company, has received a purchase order from Tsinghua University that is expected to be shipped within 2 months. In addition to the purchase of the system, Picometrix has entered into an agreement that permits its use of the university's terahertz application development lab for customer demonstrations.

The T-Ray[TM] 2000 is a laboratory instrument that produces, detects and analyzes ultrashort pulses of terahertz waves used for research and development of novel imaging and spectroscopy applications in the industrial non-destructive testing, homeland security, and defense markets. Application development is the critical first step in the adoption and widespread deployment of terahertz equipment on the factory floor and in the field. The system's patented fiber coupling permits automated or manual scanning of the sensor heads over the objects being scanned. This permits the rapid imaging of any size object, greatly improves research productivity, allows the system to operate in ruggedized environments, and eliminates the need to fit the object into specialized fixtures in order to be scanned. The industry leading signal to noise ratio of the T-Ray[TM] platform allows even thick samples to be scanned rapidly.

To date terahertz application development has been focused on detecting concealed weapons and explosives for eventual use in the homeland security market and for determining uniformity of coating thickness, performing weight and water measurements, and identifying hidden defects to insure product uniformity for eventual use in the quality control non-destructive testing market.

Tsinghua University, known as the "M.I.T. of China," was established in 1911, and has 13 schools, 26,000 students and 2,800 faculty members. With a reputation for excellence in Science and Engineering, Tsinghua produces many of China's top scientists, engineers, and business leaders.

"We are excited to be working with top researchers in China. Their selection of the T-Ray[TM] 2000 as the instrument of choice for terahertz research and application development in a competitive bidding process confirms the industry leading features and versatility of the T-Ray[TM] product line," said Richard Kurtz, CEO of API.
