This is an optical engineering question rather than anything else. So I beg for your patience.
I have an inverted microscope which we are trying to do some cancer research with to image cells.
Since this involves extended periods of imaging, we would like to integrate some OEM components in the following order.
Halogen light source on the microscope -> electronic shutter (TTL triggerable) -> specimen -> Objective -> DSLR camera.
We have all the components except the a) shutter and b) Camera. I am trying to do some background research on how I can make an informed decision regarding these purchases to integrate efficiently.
My main issue is this. The electronic shutter and the camera are from TWO different vendors. For e.g., Uniblitz for the shutter and Canon 6D (or a variant). I would need to capture an image on an average once every 10-15 minutes. The exposure time would be one minute. So what would need to happen is that the shutter is triggered by a TTL input signal causing the shutter to open and the light to come through. The shutter is the open for 1-2 minutes. The camera then clicks the picture with an exposure of 1 minute. The shutter then closes. My main trouble is coordinating this whole process. The camera needs to recognize the shutter is open and take a picture. Alternatively, I can set it up so that the opening times and clicking time overlaps according to a pre-determined schedule. That seems a bit crude of a solution.
But I was wondering if any of the experts on this forum have an elegant solution to this issue? We can spend a bit of money, but I am trying to do this on the cheap (for example, program an Arduino board to send the TTL signal to trigger the electronic shutter from a computer). I saw IR triggering described somewhere. I am basically trying to find some inspiration here.
In the name of science, thank you!
