SCANNING MIRROR ARRANGEMENT

摘要

B75-002 SCANNING MIRROR ARRANGEMENT An image forming scanning mechanism without obsuration in its optical path comprises first and second reflectors that are pivotally actuated about respective orthogonal axes. The scanning reflectors are positioned so that radiant energy in a first optical path from an object field impinges upon a vertical-scan reflector where it is directed to a horizontal-scan reflector and whereupon it is directed back onto the vertical-scan reflector from whence it is reflected along a second optical path in a different plane from the first optical path. The pivotal axes of the vertical-scan reflector and the horizontal-scan reflector are perpendicular to path of radiant energy reflected therefrom. A detector is positioned to receive radiant energy from elemental areas of an object field. The orthogonal disposition of the first and second pivotal axes provides a distortion free image signal from the detector that is comparable with the x-y scan pattern of conventional television display circuits.
