Impact in the space sector is speculated for several applications.
On the Ground.
On the test bench.
On the launch site.
On the top of the high dynamic range, Ladewifin will have 23 bits/pixel/color depth.
When the rocket crosses the upper layers of the atmosphere, the colors of the rocket become less and less saturated (diluted in white, blue or gray) especially when the sky isn’t 100% clear. The luminosity of the rocket’s flame still generates a high dynamic range. Therefore, the rocket becomes very hard to observe.
Ladewifin will be able to track rocket much higher in the sky than classic cameras on the ground.
In space.
Since moon-glare and earth-glare can disturb some space-sensors (star trackers), the parasites generated by sun-glare are an obvious challenge.
Rendez-vous and docking manoeuvres.
After missions in space, Jean-Loup Chrétien confirmed the danger of sun-glare in space while founding Tietronix Optoelectronics : another enterprise specially intended to fight blooming and glaring. Succesful spacecraft rendez-vous and docking manoeuvres require high concentration from the astronauts. Blinding glare issues from the sun its reflections on metal parts are handicaps. Ladewifin can enhance the speed and safety of these manoeuvres. Ladewifin is fully complementary with their US20090015682A1, US3276813A, US4918534 and WO2005069605A1 patents without any overlap. These solutions are modular and can reach extreme performances.
Star tracking.
the moon the earth's atmospheric layers disturbs observing the stars. Ladewifin's dynamic range large range of frame rates (up to 500Hz) are suitable to top the performances of current star trackers.
Hyperspectral monitoring.
a high frame rate a high sensibility (high fill-in ratio) a wide dynamic range no microlenses as, for example, for hyperspectral scanning.
Ladewifin provides a wide dynamic range a high frame rate a large pixel-depth a whole range of fill-in ratios without microlenses.
Microlenses boost the vertical x horizontal fill-in ratio but dilatation issues inhibits their presence in space. Option 2 meets as much as possible the requirements of hyperspectral monitoring of earth from space. * size before application of the "horizontal x vertical fill-in ratio" to get 1 photodiode's photosensible area.
Lightning imager.
Terrestrial weather observation requires statistics about lightning. The lightning average duration is 200 µseconds made up from a number of much shorter flashes (strokes) of around 60 to 70 µseconds. A wide dynamic range and high frame rate are required for correct analysis. Ladewifin can combine both.
Space exploration robotics.
The sun, torches that beat the sun, (in direct or indirect view) make classic cameras unsuitable for these applications. Ladewifin enables better scans of such extremely contrasted sceneries for extraterrestrial robots.
Debris & asteroids spotting & tracking.
Space weather.
The solar and heliospheric observatory has got a LASCO with 3 telescopes, each of them having an "exceptional dynamic range" an 1024 x 1024 resolution : the same purpose as Ladewifin with the same resolution.
