calculate time taken to travel 70cms and 40cms also calculate their difference which gives the exposure time of camera
Answers
The calculation of the correct exposure time in case of moving parts prevents blurred images. They are produced when the pixels shift in the range of the camera while being exposed. Depending on the application, different tolerances are possible. A smear effect of 1 pixel is not visible to the eye most of the time, however, it still affects precision measurement results. Yet this value is acceptable for many standard applications. Useful exposure times for CCD cameras are between 50 µs to maximally 500 ms. Typical values in practice for "normal applications" are mainly between 0.1 and 20 ms. Using CMOS sensors, shorter exposure times of up to 1 µs can be realised, too.
If the exposure time calculation gives greater values (e.g. 50 ms), it is of course possible to use a shorter exposure time (e.g. 5 ms) if there is sufficient light. Longer exposure times are also to be avoided as vibrations can also become visible in the image.
