Abstract

It is well known that the Infrared (IR) transceiver performance test is a very important stage of the research, design, development, manufacture and applications. The conventional open space and pre-calibration test system has some very serious problems: 1) Environment background reflection in an open space site affects the test results, especially for the tests with low optical power levels. 2) The output optical power from a pre-calibrated light source is not stable due to its thermal performance.
