Abstract
A multi-field imaging device is described for directing light from a first optical field and a separated second optical field into a video camera used for security surveillance thereby reproducing a split-screen image with the video camera. The multi-field imaging device can be aligned whereby light from the second optical field is directed directly onto one side of an image plane. A pair of mirrors are adjusted so that light from the first optical field is reflected by the mirrors to the image plane in a juxtaposed relation with the light from the second optical field. The image plane is positioned a predetermined distance from a lens of the video camera whereby images directed on the image plane are reproduced by the video camera.
