   Choosing dynamic or multiple exposure mode (G2xxx)

Question 

What exposure mode do I use with targets whose reflectancy or color varies? And with targets whose reflectivity or color varies along the laser line?

Answer 

Sensor Model G2xxx
Firmware Version 3.x, 4.x
SDK Version n/a

Dynamic exposure should be used when the overall target reflectivity or color varies between scans (typically found when objects of different reflectancy/color are scanned one after the other). A minimum and maximum value must be defined.

Multiple exposure should be used when a single target's reflectancy or color varies along the laser line at any given time (for example, if an object is half white and half black, and both white and black are scanned by the laser line at the same time). The sensor will automatically combine the multiple exposed images into one profile.
