Abstract:

A survey has been made of literature pertinent to the design of hand held binoculars hereafter simply referred to as binoculars intended to be used visually. This survey covered over 5,000 open and classified literature items published during the past one hundred and sixteen years, the majority of the more important works of which were completed during the World War II years. The results of the literature survey clearly indicate that the design of binoculars has not been based on visual tasks intended to be performed using such devices. It has largely been governed by preceding designs and the limitations imposed by technological skill in producing instruments at a rate said to be necessary to meet military requirements. This procedure may have resulted in the design of binoculars of higher quality and hence more costly than is required for many military purposes. Accordingly it has been concluded that the procedure of designing binoculars should be changed by making allowances for the end use to which such devices are to be put. Such allowances would include the limitations imposed by the characteristics of the target, the properties of medium between the target and the binocular, and the response of the human observer.
