摘要：

A new system for measuring the transmittance and reflectance characteristics of lightwave components is described. By employing frequency-tracked narrowband detection after optical heterodyning, a resolution bandwidth as narrow as 3 MHz with a dynamic range of 50dB is achieved at a scanning speed of 1GHz/s. The shot-noise-limited sensitivity of the system is also discussed. © 1990, The Institution of Electrical Engineers. All rights reserved.
