Report of the Projection Theory Committee

Under the present organization of the Society, there are three projection committees : namely, the Projection Screens Committee, the Projection Practice Committee, and the Projection Theory Committee. Since it is the primary function of the Projection Theory Committee to deal with the optical principles involved in the projection of motion pictures, the work of this Committee does not lend itself to the usual type of progress report. The optical principles have long been established—so long, in fact, that they are seldom discussed in the current literature. Instead, one must look for them in advanced works on optics, which ordinarily contain so much irrelevant material that a full understanding of the theory of optical projection is not easily acquired. The Projection Theory Committee feels that it can be of greatest service to the Society by preparing a short monograph on the theory of projection. This monograph will discuss the function of the light source, the condenser, and the projection lens; will analyze the requirements that must be met if these units are to work together effectively; and will indicate, by a discussion of the photometry of optical instruments, the method of obtaining the maximum illumination of the screen with a given source of light. As this report is written, the monograph is in outline form, and will undoubtedly be completed during the coming summer.
