Abstract:
Five telescopes with apertures of 60mm to 300mm and four different sensors were setup at off axis ranges of 60 meters, 800 meters, and 7.2 km from the laser guide star projection telescope attached to the 3 meter Shane Reflector at Lick Observatory. Results will be discussed in which an all night data collection was used to compare irradiance ( ph/cm2/sec) of the laser guide star from each location and sensor. The dynamic behavior observed and measured profiles will also be shown. In addition an evaluation of the irradiance collected from the Lick Guide Star Shack Hartmann sensor will be compared to our off axis sensors.
