Abstract: An acoustical holographic imaging method and apparatus for introducing a reference wave into a hologram surface such that the reference wave does not interfere with an object placed adjacent to or in close proximity to the hologram surface. More particularly, the ultrasonic holographic imaging system may use a reference wave introduced on the side of a thin (3 element) detector that acts as a wave guide; to introduce the reference wave to a liquid-to-gas interface or alternatively, from the topside of the detecting surface through a liquid-to-liquid interface. The system eliminates the acoustic lens system, thereby reducing the size and cost of the system. Further, an object may be placed at the detecting surface, increasing the depth of field of the resultant image and reducing the energy needed from the object source. The system may additionally utilize multiple reference sources.

Abstract: There is disclosed a sterilizing fog, characterized by droplet size range, vapor density range, sterilant concentration range and sterilant concentration within the droplets. Specifically, there is disclosed a fog achieved by an apparatus combining pressure, temperature and acoustics to form a super-charged ozoneated water and an apparatus that creates small micro droplets which form a highly concentrated sterilizing fog. Specific sterilants used are ozone, chlorine and chlorous acid generating compositions such as sodium hypochlorite, or combinations thereof.
