    What are the different modes of the follow spot module

    The system operates in four modes (manual operation, pre-defined motion saving/playing, auto tracking, and console operation). Follow spots, with their powerful long throw, are a staple of music concerts, skating events, award shows, theatrical performances, and circus events (Figure 20. Follow spots are typically used as front lights to highlight and set apart the performer from the rest of the stage as they move. Some common types of follow spots include: 1.


  • Planar waveguide mode

    Planar waveguide mode

    Similar to the Gaussian beam the guided mode is made up of mostly paraxial plane waves that hit the high/low-index interface at grazing incidence and therefore undergo total internal reflections. Waveguides can be as short as a few millimeters. Guiding of light with exceptionally low loss in fiber (0. 1dB/km) can be achieved by using. This article discusses propagation modes of light in different situations: in free space, in a transparent homogeneous medium, in a waveguide structure, or in an optical resonator. continuous-wave mode locking, Q-switching, or. Planar waveguides, also called slab waveguides, are waveguides with a planar geometry, which guide light only in one dimension.
