Active reacking using image of the RIS

4. Results - Active tracking using image of the RIS

Active tracking of RIS was established using an image of the RIS lit by the second harmonics Nd:YAG laser at 532 nm. Figure 4-1(a) shows the reflection from the RIS at 532 nm taken with an ICCD camera for coarse tracking on the guide telescope (20 cm in diameter). Figure 4-1(b) shows an image taken with the ICCD camera for fine tracking which is installed in the Coude system of the tracking telescope. The field of view of the Coude ICCD is approximately 200 microradians. The tracking accuracy of approximately 30 microradian was achieved with the active method both in daytime and nighttime.
