With the advent of Ranger probes and more advanced reconnaissance systems, telescopic photography will continue to play a significant role in the study of the lunar surface during the next few years. A new astronomical camera has been designed and fabricated in support of the Air Force lunar charting program at ACIC, and the features incorporated into this design make it one of the most accurate photographic tools ever used in the field of astronomy.

Light attenuation measurement techniques will be discussed and typical data presented. Measurements taken near San Clemente island will be presented of the volume attenuation coefficient, diffuse attenuation coefficient, and spectrographic characteristics. Typical volume attenuation measurements taken in the north Pacific at depths to 6000 feet will also be presented.

Discussed are the methods used in photographing contaminate particles of less than .006" size inside transistors while subjected to various frequencies and vibrations. Observation of wire forming dies and electrode welding of header posts in automatic equipment and a suggested method of adapting a microscope into a camera taking lens.

The human eye must be pointed very accurately at detail of interest if this detail is to be seen with maximum clarity. The physiological eye-pointing servo is a vital, not incidental, part of human vision. The neuromuscular system that controls eye direction is very highly developed. It has been suggested that this neuromuscular system might be used, in certain appropriate cases, as a new means by which man can control a man/machine system. That is, that the eye muscles be used in place of, or in addition to, conventional hand action. In this way man's capability for action in high performance man/machine systems might be usefully extended. In order to apply the concept to eye control, it is necessary to have a transducer (oculometer) that can measure eye direction without interfering with the human subject.

Optical elements may be separated into two classes: (1) Solid Optics, and (2) Membrane Optics. Solid optical elements - such as glass or plastic lenses and glass or metal due to crystalline structure. Grinding and polishing reduces these surfaces to an amorphous atomic condition similar to that of liquid surfaces. Membrane optical elements - such as the cornea of the human eye, the Wood rotating mercury paraboloid the IRCO electrostatically-figured membrane paraboloid and the "Orbiting Eye" possess initially smooth and symmetric surfaces. The aspects involved in the development of this "Eye" are discussed by its inventor.
