Abstract

PURPOSE: To enahce the detecting accuracy of a focal point with the use of a simple construction by receiving the fluxes of light of a range finding lens in different direction through a grid with the use oftwo light receivign elements so as to make use of the difference in frequency between the respective contrast signals and output signals.
