Project Status: Eye-safe lidar receiver and data acquisition
The custom 16" telescope primary is located near the floor (see left pic) and the
secondary is a flat that simply redirects the converging receive
rays toward receiver optics on the top of the optics table (see right pic).
New (delivered 28 August 2003) telescope optics have gold coated surfaces for high reflectivity in the NIR.
The following pic shows our eye-safe lidar data acquisition computers.
The older P3 on the right contains the 14 bit 100 MSPS digitizer card
and runs Labview software under windows for data display and recording.
Data files are saved via
a network connection on the new Linux box (eyeball) on the left.
We use IDL and BSCAN to display the images.
Bruce Morley designed the following dual-channel receiver for our work at 1064 & 1543 nm. It uses a short-wave pass dichroic to split the beam. This photo shows a New Focus InGaAs PIN on the left and a LiCEL Si APD on the right.
Here are pictures of our single channel receiver for work at 1064 nm only.
It couples our 16" Meade telescope to a turning mirror, interference filter,
iris diaphram, and a LiCEL Si APD detector module.
