  can uncooled microbolometers be used for ground based observations of deep sky objects? I assume that integration time and noise will be an issue - but I have yet to see it done or disproven. Some of the brighter objects should be M42

  I don't even know if you'll get this notification, but thanks for those shots. I was looking for this kind of footage to compare with the fireworks in the movie Dune 2. The sun there is shining only IR light. And they have fireworks but it's so unnatural. The movie FX are really authentic, so it's a good comparison. Thanks again

  Hmmm, while this is very impressive demonstration on its own, one can't help but wonder about how much operational relevance it actually has. Sure the drone was "detected" 4km out. But only as a tiny blurry blob, and with the system staring directly at it. The website states the camera system's FOV is "8.8º-0.6º", so to get solid coverage of the entire horizon at that distance would require... a lot of these! I didn't see a price listed on the site, but I can't imagine that'd be cheap. Furthermore, even with the most advanced AI assistance, it must be incredibly difficult to identify a threat in all the noise of moving background, birds, bugs, turbulence, etc. So even having the drone in-frame wouldn't guarantee detection. The fact the video editor decided to use a circle to highlight the drone in these clips speaks to that. All in all, not really sure what this test proves in regards to dronetection. The Ventus could certainly be useful in conjunction with some sort of hybrid integrated sensor network, but that's not what was discussed above. What'd be fun and would prove a lot more is to zip-tie a paperweight to the bottom of a Mavic and see how close a pilot could get to directly over the observer before the drone was spotted. As the pilot and spotter got more experience and switched off, it'd get progressively more challenging for both as the pilot tried different tricks and the spotter got better at spotting. That'd get some actually relevant numbers.

  Dead Pixels do happen from time to time and can easily be adjusted by a FCC. However, if the bad pixel remains we flag it and do what is called a, "Dead Pixel Replacement" test.

  Look at the size of that lense...I can't imagine how much it cost??

• 
  @SierraOlympia5 ай бұрын

  It's a common misconception that the size of the lens directly correlates with the cost of a camera. It's important to note that mid-wave systems require additional cooling, contributing to their higher cost compared to long-wave systems, which don't necessitate the same cooling setup. So, while these cameras are indeed expensive, the size of the lens alone doesn't determine their price.

  I think in another comment you mentioned the sensors in the video are semiconductors, eg the ir photons are jumping a band gap to send a signal down the sensor leads. IR photons have wavelengths in the few um range, so is that what's limiting the resolution of the sensors? RGB sensors could be packed 100× more dense, given 0.7um photons in the red part of light vs 7um photons for MIR in a 10×10 array.

• 
  @ZevHoover4 ай бұрын

  it is part of the limit, yes. Where as you see modern phone sensors with 1um pixels, you will never see a LWIR sensor with a pitch that small. With that said, most RGB sensors have pixels in the 3-6um range, which could work fine for SWIR and much of MWIR, its just the technology has not quite gotten there yet.

• 
  @Veptis4 ай бұрын

  ​@@ZevHoover it's been several years since Iray has announced a 8μm pixel pictch microbolometer for lwir. But I haven't seen it in a product. You also can't compare microbolometers with with CMOS or even CCD pixels. The gaps between the active collector area is quite notable and the fraction of active area fraction scales by a square. Leonardo DRS has a special umbrella shaped design for their pixels. It's more area efficient than other microbolometers and therefore their tenum (10 μm pixel pictch) models make viable products. My own collection has 35, 25, 17 and 12μm pixel pitch sensors... I haven't yet compared them well enough

  Is there a vacuum between a front lense and a microbolometer?

• 
  @SierraOlympia7 ай бұрын

  It varies based on the sensor type. In this video, we feature the Athena sensor on the Vayu HD, and it indeed incorporates a vacuum between the lens and the sensor for optimal performance. However, it's worth noting that the Tenum 640 follows a different design and doesn't utilize a vacuum in its configuration.

  What is the benefit to 10-12 micron over a 17 micron?

• 
  @SierraOlympia9 ай бұрын

  Great question! A 10-12 micron pixel pitch offers significant benefits over a 17-micron pixel pitch in thermal imaging. Smaller pixels deliver higher resolution, sharper images, and improved detectability. They can discern finer details, making it easier to detect and identify objects at a distance. Smaller pixels also allow for a reduced minimum focus distance, which is advantageous in scenarios with limited proximity to the subject. However, the choice between pixel pitches should consider the specific application's requirements and potential trade-offs, as 17-micron pixel cameras may excel in different long-range surveillance scenarios.
