Miro 2 Notes

The Phillips screw in the bottom corner of the camera secures the battery compartment door.  I temporarily labeled it.

The compact flash (CF) card is inserted with the label oriented towards the front of the camera.  I have this labeled.

The allen screw above the CF card label secures the threaded collar that the lens mounts to.  When this is loosened it
should allow the collar to be adjusted.  I tried this and the collar was still stuck.  The lens back-focus is off slightly.
You could open the camera and free-up that collar but I didn't want to break the factory sticker.  The easiest and cheapest
solution is to add a macro extension ring (basically a washer) on the threads of the lens.  The practical reason why you may
want to address this is because how close or far away the lens is from the image sensor determines the lens back-focus.  In
this case, the lens mounting closer to the image sensor makes the lens' closest working distance farther than specified on
the lens range scale.  So the lens may have a mark for 3ft but when the lens is focused to that mark, the focal plane is at 3.5ft.

The camera takes 1 inch format C-mount lenses.  Most C-mount lenses are 2/3 inch format.  If you use 2/3 lenses, it will vignette
and appear like you are looking through a tube or tunnel.  I recommend buying a C to Nikon F/G lens adapter: https://amzn.to/3VUvmv9
and using fast f/1.4 lenses.  Rokinon, Samyang, and Bower are all fairly inexpensive yet sharp.  Zeiss Planar T lenses are great.

The camera will operate either by LCD touchscreen or over Ethernet to a PC. For Windows 10 or newer use the PCC3.X.  For Windows 7
I recommend using the PCC2.X.  The ethernet is not 1 gigabit, its a slower protocol.  But I have a document on how to setup your
IP address network settings to connect.  Basically you need to change your local area connection IPv4 properties to IP 100.100.100.1
and your subnet mask to 255.255.0.0 you may need to also permit the PCC software through your Firewall.  I can walk you through this
by phone. I recommend PC control over LCD because you will have full control of camera settings.

I included the Aimed Research Camera Setup Calculator (ARSetupCalc).  This is very useful to simulate conditions to determine what is
needed or expected before engaging a project.  You need to input the camera's pixel size in micrometers (um).  I have experimentally
determined the Miro 2 to have 22um-sq pixels.  Pixel size is the most important input!  The Bit Depth is 8-bit.  The memory is 1GB of RAM.
You can calculate the field of view with a given lens focal length, resolution, and object distance.  You can determine the projectile
travel per frame period for a given frame rate and object velocity.  You can calculate the motion blur in terms of pixels or field units
for a given velocity and exposure speed in microseconds (uSec).  Depth of Field is more a qualitative reference because the formula relies
upon a value termed the "circle of confusion", so its not a sharp measurement.
