South Korean Inventors Develop Bolometer Compensation Circuit
|
ALEXANDRIA, Va., March 14 -- Hee Chul Lee, Chi Ho Hwang and Yong Soo Lee, all from Daejeon, South Korea, and Sang Gu Kang of Gyeonggi-do, South Korea, have developed a bolometer.
According to the U.S. Patent & Trademark Office: "The present invention relates to a bolometer, and more specifically to a compensation circuit for compensating non-uniformity due to the difference of operating temperature between bolometers which exist in bolometer array using semiconductor material."
An abstract of the invention, released by the Patent Office, said: "A compensation circuit according to the ...
