Abstract
A solid state laser visible light source (26) passes light through a scanning mechanism (22) otherwise used to convey radiation from a target (12) to a detector (28) of a scanning radiation sensor (10) to mark with light a line (16) which is continuous when the sensor (10) is operating in a continuous mode, but when the sensor is operated in a spot mode in which a plurality of spots along a scan line are to be individually measured, a control (30) causes the light source to turn on and off at the correct times in the scan cycle to cause the light source (26) to mark the plural spots on the scan line (16). A CCD camera (40) with an automatic gain control circuit (46) is used in conjunction with a band pass light filter (36) to substantially enhance viewability of the image of the light markings (16) on the target (12) on a display (44).
