Just something ive been mulling over for a few months now...
I'm not referring to thermal imaging, but just standard IR spectrum viewers. I've seen several baby monitors and the scores of game cameras based on this technology, all for less than $400(sometimes significantly so). I can't help but think that if someone were to adapt the tech to a goggle and ruggedize it that it would be a great low cost alternative to traditional NV devices. Obviously this wouldn't be practical for military purposes because you'd need a constant IR light source, but I think that most civilian and even LE purposes it would work great. I'd rather use it in situations where my alternative would only be a visible light flashlight. And no, I'm not referring to the "cyclops" toy goggles (or whatever they were) someone posted in another thread 
Anybody else have ideas along these lines? |

There had been. It was called Xenonics vision. It's also on some Sony digital camera too in "Night Shot" mode, where a "hot" filter is removed for night use. You will hear a click when this happens.
Regular night vision also respond in near IR. If you really want an explanation, "hot filter" removes near IR (NIR) spectrum (700-1000nm). You can also "up" the integration time, which is equivalent to exposing the camera longer (think longer shutter). You can only expose for so long due to smearing issue (which will be different depending on optics chosen) and/or frame rate - 30 frames per second will limit the integration time to 1/30 of a second (add read-out time too of course) before you have to start read-out the next frame. |

xGen... Opticsplanet sell them... $120... Great toy for the kids. But most people here want passive NV, so it's either cascade or Gen2 as a starting point :) Regards David Thanks for the replies, folks. Yes, I too would rather have true passive NV, but it just seems like a more economical yet still useful alternative would find quite a market. Especially if it was designed to interface with standard PVS-14 accessories, mounts, etc. |
