One hundred and eighty degree objective for monostatic coaxial LIDAR telemetric system

摘要

The one hundred and eighty degree objective for a spectral band viewer has a laser with a lens producing a real image of the laser beam. There is an apertured mirror at forty five degrees and surrounding the laser beam. A fibre optic extends between the laser image point and the output at the centre of the telescope. The objective has a detector and a focussing lens.
