OBJECTIVES FOR DEVELOPMENT OF TEST BENCH FOR PROJECTION METER
The author addresses the issue of resuming research in the field of development of projection meters using advanced technologies. The need for a lab test bench is substantiated. The main objective for the test bench design is formulated as the presence of geometrical elements (points, axes, planes) matchable with geometrical elements of projection meter. The classification of geometrical elements and the requirements for their ratio are developed for the projection meters and the test bench.
