| Popis: |
The performance of a frequency-shifted feedback laser (FSFL) using a Nd:YVO4 crystal as gain medium was investigated as light source in high accuracy optical ranging based on optical-frequency domain reflectometry (OFDR). The FSFL generates a comb of chirped frequency components over a bandwidth of 45GHz with chirp rates of 3.8×1017Hz/s. In OFDR, distance accuracies better than 25um at a data measurement time of 2ms were demonstrated at a standoff distance of 5m. The results show that the FSFL is a promising light source for high accuracy, high speed 3D measurement applications. |
