How to Freeze the Motion
When a moving object (e.g. on a conveyor belt) is imaged with a longer exposure time, the resulting image will show Motion Blur. To avoid
Motion Blur the short exposure times or flash illumination should be used.
Example of a setup with MU9 camera:
Sensor width (W) 0.0057m
2520 pixel horizontally (PX)
Field of view (FOV) 0.2m
Conveyor speed (CS) 0.1m/s
To contain Motion Blur to within one image pixel the following calculation for the flash light duration may be used:
Pixel distance (PD) W/PX -> 0.0057m/2592pixels = 2.2um.
Pixel distance recalculated FOVPD = FOV/PX = 0.2m/2592 = 77.2um
During exposure the object should not move more than 77.2um
Flash Time (FT) should be less than FOVPD/CS = 77.2um/0.1m/s = 0.772ms
