Disclosed is improved sensor apparatus for guidance systems, and the sensor apparatus includes means for receiving light reflected from a target and for processing this light to provide steering signals to the missile guidance and control mechanism; more specifically, the sensor apparatus includes means for receiving a single pulse of light reflected from the target and for forming a two-dimensional image therefrom, quantizing the data from the image, and re-forming the quantized data into a straight-line image from which a time-dependent signal is generated to be input to the missile control mechanism.

DETAILED DESCRIPTION What is claimed is: 1.
Sensor apparatus for guidance systems, said sensor apparatus comprising: means receiving light of a single pulse reflected from a target area and focusing said reflected light to form a two-dimensional image, means receiving said two-dimensional image and operable to convert said two-dimensional image into a quantized, straight line image, means receiving said straight line image and converting said straight line image into a two-dimensional display wherein each quanta of said straight line image is displayed in a time-dependent position, means receiving said two-dimensional display and converting said display into an electrical signal, steering control means forming a part of said guidance system, and means applying said electrical signal to said steering control means.
2.
Sensor apparatus for guidance systems, said sensor apparatus comprising: lens means receiving light of a single pulse reflected from a target area and focusing said reflected light to form a two-dimensional image; a fibre optic bundle having input and output ends and formed of a plurality of light-conducting fibres oriented adjacent the input end of said bundle to define a two-dimensional area approximating the size of said two-dimensional image and positioned to receive said two-dimensional image, and oriented in single file adjacent the output end of said bundle to form a straight line image; a scanable image converter tube having a photocathode positioned to receive said straight line image and including means for deflecting electrons emitted by said photocathode in a time-dependent manner and in a direction perpendicular to that of said straight line image to provide a two-dimensional display; means for receiving said two-dimensional display and converting said display into an electrical signal; steering control means forming a part of said guidance system; and means applying said electrical signal to said steering control means.
3.
The sensor apparatus of claim 2 further comprising: light source means emitting periodic pulses of light to illuminate said target area
