Abstract: Disclosed is an imaging device employing a measurement zone directed at a target, where the imaging device can be used in conjunction with a misalignment analysis feature. The imaging device can capture first and second images at different times. The first and second images may be compared, such as by comparing a location of the measurement zone of the imaging device in the first image with a location of the measurement zone of the imaging device in the second image. Based on the comparison, a misalignment indication of the imaging device relative to the target can be provided.

Abstract: A scanning radiation sensor (10) automatically focuses a focusable optical system (26) based on the closest distance (C) and the farthest distance (F) of the optical system (26) from a target (12) through means of a focusing controller (44), motor driver (42) and focus motor (40) to obtain an optimum focus for all points along a line between the farthest point (f) and closest point (c).

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).
