Abstract

Abstract A laser type direct fire weapon simulator for action against a moving imageisplay wherein the weapon is slaved connected to variable voltage producing devices such as potentiometers to provide voltage outputs corresponding to azimuth and elevation positions of the weapon, a voltage responsive beam deflector system for varying the direction of the laser beam on the display target in accordance with the azimuth and elevation voltages, a continuous reading delay monitor responsive to a delay voltage derived from the elevation voltage to provide prior time readout voltage data to an electro-optical system directing the laser beam such that when actuated the system shows the location where a missile would have hit allowing for delay time corresponding to elevation voltage, together with a delay trigger circuit which delays the display of the hit until the elapse of missile flight time corresponding again to elevation voltage and hence range. The invention further contemplates adder circuits and instructor adjustable voltage input sources to vary the azimuth and elevation inputs to the electro-optical system corresponding to selected v-parallax and ballistic data.
