Yep, sometimes the journey is more important than the destination.
I regularly build things I could have more simply bought, for this very reason. At the end I have the thing I wanted plus a lot more knowledge.

I still think the Arduino is pointless to use for a night vision device.a camera connected to a screen is all it takes.the Arduino would just be an unnecessary piece that doesn't contribute anything other than complicating things.to modify a video camera with a laser attachment is the simplest route.

If it's mobile on a gun handling video... I'd suggest an FPGA over an ardunio or pi as I'd expect the FPGA to last a lot longer on battery and it would be lower latency (not sluggish/delayed frames). An ardunio or pi may last a long time under other use cases, like sampling at 1Hz then using power saving "sleep" modes the rest of the time.

Personally I wouldn't do 25fps or whatever the sensor can handle but do 4fps or something to conserve battery. And read up on the power saving features the hardware has and use them.

I guess it could do some processing to autofocus on warmer areas, depending on whatever focusing system the camera has.

At a glance these are the tools I'd look into, Icestudio would be my preferred environment:

But I'm sure you could find many 'FPGA computer vision' project starting points:

The Jetson Nano looks like an interesting platform. To go with it, Unity and OpenCV look like cool augmented reality programs to play with

I just wanted to post this:

This is a data sheet for a M01_4K_V3.0 HDMI to MIPI driver board. I am using this for my project. It connects a regular HDMI cable to a phone screen, such as:

https://www.ebay.com/itm/5-5-inch-1920-1080-LCD-Display-3D-P...

I had to get this data sheet from a Chinese supplier, so I am posting it for the public.

Update

I am working on the new display and driver housings.

Here is an interesting IR camera project using a raspberry pi zero and NOIR camera

https://robotstyles.blogspot.com/2018/04/gavino-unas-gafas-d...

The range is short and it uses wifi to transmit the video.
