How can I choose high speed camera about shown bubble on air-water flow? Which properties have I to determine on camera? Which properties are important, resolution or etc.?
I need high speed camera and post processing of the images taken during the experiment for analysis for finding bubble diameter and terminal velocity and frequency of bubbles ... please suggest me with best options
We have built a kind of light source that can produce both continuous and pulsed (500 ns) light. When we tested with the continuous mode (dark room and target was a glass of water and dirt) the target was beginning to shine but in pulsed mode the only thing that we could capture was just a thin arc around that glass (the mixture of water and dirt was completely dark and unseen). But why? In my theory there is not any difference between pulsed and continuous light just in making blurred image or sharp image of a moving object!
I have a pulsed laser (~10ns pulse) which I want to use to image droplets at high speed. I couple the laser into an optical fibre with a micro lens and then produce a collimated beam from the output of the fibre. This is then used as a backlight for the imaging. Does anyone have any suggestions on how to remove the speckle? (Spatial filtering? Diffusers?)
I want to drive a compressor up to that speed as a starter.
then, driven by a turbine, it must be capable of working at some 45 KRPM and produce 1 KWe.
I have a NI compact DAQ (cDAQ), used to acquire analog data from various sensors. Also have a high speed video camera with GigE controller.
Is there any way to trigger the video camera using cDAQ so that I can acquire analog and video data simultaneously??
(Note: I realize that, if it is possible, I may need to purchase a specific cDAQ module for the camera, but for reference I currently have the following modules - 9203,9205, 9233, 9234, 9239, 9481).
I am using a high speed imaging system that gives me about 2s long videos if I record at speeds around 3000 fps. I wonder whether or not this is enough time to a welding defect, as for example humping phenomenon, occur. Assuming that the trigger system works well and the camera starts to record at the moment the defect start to form. I also found few references in the literature on the application of high speed imaging to detect welding defects.
I really appreciate your help. Thank you so much.
