Adaptive laser optics

Adapting the system to a mobile unit involved redesigning the instrumentation for portability and mounting it into a 3 A x 5-ft steel cart. A major requirement for this unit was containment of the Line-Lite laser, optical elements, and detection module in a clean laboratory environment. Other requirements included high ground clearance, accessibility to electricity within 100 ft, and durable construction. The entire mobile unit can be powered by a 5-kW gasoline generator. [Pg.234]

For all applications in spectroscopy it is necessary to adapt the optical conductance of the fiber to the other elements of the instrument. Laser radiation can be transported easily by one fiber, but its connection to a spectrometer principally needs a bundle of fibers, because spectrometers have an optical conductance which usually exceeds that of one fiber. Besides, irradiation of the entrance slit of a grating spectrometer requires the fibers to be arranged in a row, while an interferometer requires a circular arrangement at an image of the Jacquinot stop. The optical conductance of one fiber may be approximated by... [Pg.105]

Movements of single myosin molecules along an actin filament can be measured by means of an optical trap consisting of laser beams focused on polystyrene beads attached to die ends of actin molecules.

Figure 1. Schematic of a laser guide adaptive optics system. The laser is pr( jected along or parallel to the telescope ax onto the science object. The deformable mirror can be a separate entity, or can be an adaptive secondary. The light is split among the cameras by dichroics. Figure 1. Schematic of a laser guide adaptive optics system.

Abstract We explain the laser guide star concept and why we do need laser guide stars (LGS) to greatly enhance adaptive optics performances at large telescopes. Then we discuss the two physical limitations of LGS, which are the cone effect and the indetermination of the tilt of the incoming wavefront. Solutions to overcome them are explained. [Pg.249]
