DEFINITION

Classification: 359/1

HOLOGRAPHIC SYSTEM OR ELEMENT:

(under the class definition) Subject matter wherein apparatus for forming a record of the phase and amplitude information of a wavefront where the information can be used to reconstruct the original wavefront; apparatus to reconstruct the original wavefront from a record containing the phase and amplitude information of this wavefront; or the record itself is recited.

(1) Note. This subclass is the generic locus for subject

matter relating to holography. However, where particular use or application is claimed, classification is in the appropriate use or application class.

(2) Note. Nominally claimed subject matter external to this class in combination with holography is classified here. Significantly claimed subject matter external to this class in combination with holography is classified in the class appropriate to the external subject matter.

(3) Note. Interferometers are excluded from this subclass and are classified in Class 356, subclasses 345+.

(4) Note. Holos:graphic memories including those having a nominal recitation of a photodetector or photocell are included in this or the indented subclasses. Static holos:graphic storage and retrieval systems having electrical circuitry are classified in Class 365.

(5) Note. Dynamic holos:graphic storage and retreival systems having eletrical circuitry are classified in Class 369.

(6) Note. Mere nominal recitation of developing, fixing, bleaching, or etching a photos:graphic recording medium does not exclude the subject matter from this class. Holos:graphic systems including significant chemical processing steps are classifed in Class 430, Radiation Imagery Chemistry: Process, Composition, or Product Thereof. (7) Note. Systems for making holos:graphic matched filters are included in this and the indented subclasses.
