Equipment and process by which an operator can set a time sequence of coatings of oxygen with increasing oxidation potential for in-situ treatment of organic compounds ranging from superoxidation to reduction conditions involving hydrogen sulfide gas is described. A guide slot is formed in each of the aperture blades, and an engaging pin is engaged with each of the guide slots. The rotor blade further defines a span and a chord. The flexible safety member has face portion transversely situated and having a safety feature disposed to the needle and that slides thereon. Reference display metadata, used to guide the subsequent processing and display of the video data, is dynamically generated at the post-production stage and embedded into the video data. In addition, a third polarizer is coupled to the first output of the PBS in order to filter or block any TM light, for example, that may be output from the PBS with the TE polarized signal.
