ABSTRACT:
An ellipsoidal reflector system concentrating energy utilizing two effects- one being that light passing through one focus of an ellipse will tend to line up with the major axis after each reflection, combined with the other in the properties of ellipses rotated off-axis having one distributed focus and one point focus. After a few reflections light having originally passed through one focus is, for practical purposes, running along the major axis even though the major axis is approached as an asymptote. This energy concentration system would be quite useful as a source of highly collimated light such as would be more practical for field surveying work than, for example, lasers, for optical alignment, and fiber-optic carrier media input. In addition to light some of these ellipsoidal reflector systems for concentration of energy are also effective for ultrasonics and/or shock waves.
