ABSTRACT:
An apparatus (10) for aligning and calibrating scene displays in an aircraft simulator (12) has a base (18) on which all of the instruments for the aligning and calibrating are mounted. Laser (26) directs beam (28) at double right prism (34) which is attached to pivoting support (36) on base (18). The pivot point of prism (34) is located at the design eye point (DEP) of simulator (12) during the aligning and calibrating. Objective lens (60) in base (62) is movable on track (64) to follow laser beam (28) at different angles within the field of vision at the DEP. An eyepiece (50) and a precision diopter (56) are movable into position behind the prism (34) during the scene evaluation. A photometer or illuminometer (70) is pivotable about pivot (74) into and out of position behind the eyepiece (50).
