THERMAL IMAGING DEVICE WITH SCANNED LIGHT EMITTING DIODE DISPLAY

A thermal imaging device (10) includes a detector (50) having a linearly-arrayed plurality of spaced apart detector elements (50') upon which portions of a viewed scene are sequentially scanned by a scanner (22) in order to capture image information from the scene. A display device (22, 62, 66) similarly includes a first linear array of plural spaced apart light emitting diodes (LED's) (62') which provide light scanned by the same scanner (22) to a user of the thermal imaging device (10) to provide an image replicating the viewed scene. The LED's (62') of the display (22, 62, 66) are configured so that sequential portions of the image are interlaced and partially overlapped by the scanner (22) to provide a flat visual field which is free of raster lines. The display device (22, 62, 66) includes a second linearly-arrayed plurality of symbology LED's (198) which are configured and positioned relative to the first plurality of LED's (62') so that light from these LED's is interlaced but not overlapped and so that symbology imagery presented by the second plurality of LED's (198) is superimposed on the scene image presented to the user of the thermal imaging device (10).
