In order to research related edge plasma physics and accurately measure electron temperature and electron density with Thomson scattering system in HL- 2A Tokamak device, a new kind of near infrared (NIR) bremsstrahlung emission measurement system with high space- time resolution is built for the first time. Under different discharge and heating conditions, the bremsstrahlung signals in NIR range are successfully obtained and compared with those in visible and soft X- ray range, so that the reliability of the NIR system is confirmed. The radial profile of the NIR bremsstrahlung signals is presented by Abel inversion of bremsstrahlung emission from fifteen horizontal chords which axisymmetrically distribute along the plane in the cross section.
