receiving and outputting optics for the CLidar technique are bistatic (non-zero perpendicular distance between receiving and outputting optics). The signal strength is also much more constant than a lidar signal which can change by many orders of magnitude. It has very high altitude resolution in the lower atmosphere. The instrument components are typically simpler than those in the lidar also.

It is important in the analysis that the optics, the wide-angle lens in this case, accurately maps equal angles onto an equal number of pixels throughout the 100 degree field-of-view.

The CLidar technique has the advantage over the lidar technique of being able to measure all the way to the ground. This difference derives from their distinct geometric configurations, where in the lidar technique the receiving telescope and sourcing optics are monostatic (axially aligned) while the

In the second figure, an image from the CCD camera is shown which is analyzed by adding up the individual pixels at each altitude. The camera was 122 meters from the vertically pointed, circularly-polarized laser beam. The beam is brighter near the ground due to near-ground aerosols. A bright spot

due to a cloud can be seen near the top of the beam. The beam was positioned diagonally on the CCD array to use the space more effectively. A lighthouse and power pole can also be seen in the image.

Disadvantages include poor altitude resolution in the upper atmosphere, difficulty designing optics that gathers substantial amounts of light, and a loss in noise rejection (
