Publisher Summary Raman optical activity (ROA) is the difference in the intensity of Raman scattered light with respect to right and left circularly polarized incident or scattered radiation, or both. The form of ROA defined with circular polarization modulation of the incident laser was first described theoretically in 1971 and was first measured in

Overview of the LSST active optics system
Astronomical Telescopes and Instrumentation, 2014The LSST will utilize an Active Optics System to optimize the image quality by controlling the surface figures of the mirrors (M1M3 and M2) and maintain the relative position of the three optical systems (M1M3 mirror, M2 mirror and the camera).

The Journal of Chemical Physics, 1987
Optical activity generated by the rotational normal coordinates is investigated. The theoretical formulation is based on classical principles and uses the definition of the rotational normal coordinates and the changes in electric and magnetic dipole moment components along the principal axes of inertia due to rotations represented by these coordinates.

The Giant Magellan Telescope active optics system
Astronomical Telescopes and Instrumentation, 2014The Giant Magellan Telescope active optics system is required to maintain image quality across a 20 arcminute diameter field of view. To do so, it must control the positions of the primary mirror and secondary mirror segments, and the figures of the ...

Fast active optics control of wide-field telescopes based on science image analysis
Astronomical Telescopes and Instrumentation, 2014We study a novel active optics control scheme at the VST on Cerro Paranal, an f/5:5 survey telescope with a 1x1 degree field of view and a 2.6m primary mirror.

Wavefront sensing and the active optics system of the dark energy camera
, 2014Wavefront sensing and the Active Optics System (AOS) of the Dark Energy Camera (DECam) at the CTIO 4-meter Blanco telescope are described. DECam utilizes four pairs of intra/extra-focal CCDs located on the edge of the focal plane for wavefront sensing ...

Adapting large lightweight primary mirror to space active optics capabilities
Astronomical Telescopes and Instrumentation, 2014The next generation of space telescope will use large primary mirrors to achieve high angular resolution. Due to weight constrain, these large mirrors will have a very low mass per unit area.
