SPI Posts Color Videos at Starlight with No Moon

The latest crop of SPI color night vision videos specifically states that they are shot at starlight with now moon. The first video uses 50mm F1.2 lens:



The second video was shot with 80mm F1.4 lens:

  1. That is impressive, the noise level is in line with their other clips that display less noise with higher lighting availability, it will be interesting to see where this group takes their technology to. Looking at their web site it looks like it will be catered towards defense and security, but I can think of a handful of useful real world applications that can benefit from high sensitivity colour low light sensors. Cheers

    1. This sensor would be great for drivers and piloting aid, fused with long wave IR would make an impressive imaging package for surveillance. The amount of noise is acceptable for no moon conditions, I would like to see as well where this technology goes.

  2. Can someone provide a quick explanation of the light beam? Sorry for the ignorance question, but I'm confused at what I'm looking at. Thanks in advance.

  3. At least it's more plausible. In fact there seems to be "real" photon shot noise. The previous videos lacked it too much, I guess due to bright moonlight, artificial light and a wide opened lens there was enough illumination far beyond 1mlux.

  4. Looks like an Infrared laser

  5. It's a NIR laser pointer . When IRcut filter is used, NIR goes through and causes purple color on image since it enhances much more blue channel than others.

    1. ... IRcut is not used ...
      sorry for the mistake !

  6. That is incredible especially it being color.

  7. as I wrote in the previous blog, these 2 videos with the infrared lasers are @ 1 millilux as the title states, that is truly amazing quality especially in color. I2 nvg's with the latest tube image intensifiers can't image that good in green. I would love to see a real time demo, if SPI video is accurate and the product somewhat small, affordable and not too power hungry, this is literally game changing tech in the world of low light, and would be quite appealing to military and defense agencies.
