Hi,
Interested to see if there would be interest for a low cost hyperspectral imager (N bands) lightweight sub 300gr with a spatial resolution of 2-8 Mpixel per spectral band.
Projected unit cost would be $12,000 or less. We estimate to be able to produce 10 bands with a relatively narrow band at 20-50nm per spectral band.
Thanks

Hi Darius,
can you point me towards a Light Hyperspectral Imager to start out, all the systems Ive researched have been above the 7000 price tag.
thanks!

Thanks Trias,
My experience is limited to spectroscope imaging affected by lower sensitivity so I can assure you, DIY spectroscopy cannot compete with hyperspectral imaging offered by Gamaya and others.
In theory spectroscopy imaging has no limits on number of channels
since recorded spectrum is continuous, pixelized on saving to a vector (one dimensional array) to match resolution of CCD array.
I am developing (DIY) spectroscope camera with built-in digital filters to process channels and image layers on-the-fly into real-time (live video) visualization (camera display) to progress with night vision.
Frankly speaking I was not aware of any public interest in multispectral camera.
RaportUAS MD,
I am confusing nothing. DIY built spectroscope can act as multispectral camera
since 3D cubes are generated on-the-fly.
Ok, I would like to test micro hyperspectral sensor by Gamaya since technical data and specification are misssing.
All I need to know is sensor resolution ( clock frequency, optical lens resolution)
- distance between 2 points on the ground remotely scanned by HSI from a drone.
For 100 micro bands we need 100Hz clock to control piezo in the interferomer to scan 100 bands ( for a single point).
Since micro HSI is hoovering over the ground at some speed, all I need to know is
if 1m (distance) resolution is a limit since at 1m/s speed (3.4km/h)
a distance of 1m is travelled within 1 second.
If you need to get points on the ground scanned every 10cm, so HSI should be clocked 1KHz (piezo) or 10KHz at 34km/h speed.
Spectroscope as HSI has alike scan speed but I need higher sensivity sensors to work.
BTW
It looks like my original submission has been deleted :(
Martin,
how much is your HSI camera for tests ?
I would like to perform a number of r&d (conference) studies in Forensic Agronomy based on your HSI imager.

Ok,
from factsheet
"
Camera moduleMax frame rate16 fps16 fps16 fps30 fpsExposure time20 μs – 1 s20 μs – 1 s20 μs – 1 s20 μs – 20 ms"
==
How can it work if in case of 16 channels,
at frame rate 16 fps
your expsure time can be up to 1s
If exposure time is 1s so your frame rate is < 1 fps
not 16 fps as stated.
Could you kindly explain it to me ?
Martin,
how much is your HSI sensor/ camera ?
I have studied hyperspectral imager by NASA
and employed hyperspectral imaging analysis to detect faulty, low-performing PV solar panels on Solar Farms world-wide.
What can I suggest is to start from Light Hyperspectral Imager at $120
then move to Medium Hyperspectral Imager at $1,200
and finally move up and up with a price if market is already built and demand clear.
Do you know any demand for Light Hyperspectral Imager at $120 ?

Can you define "light" and "medium" ? AIS sensors used by NASA are surely not coming from these categories..
I guess if it would be so easy, it would be done already but as RaptorUAS pointed out, you need a significant investment to create such low cost device and bring it to the market. That's not that easy..
There are already lightweight AIS sensors available but it's still over 40000 USD. And by that I mean 100 narrow bands, not 10 wide bands system which falls into multispectral category..
Hi Michal,
It took me 5 years to make a shift from Global Warming to Climate Change terminology among UN Agencies and other bodies.
I have spent 2 years with multispectral imaginery of the Sun's activity provided by NASA to establish relations between Sun's activity cycles and Climate Change
to build another better-grounded terminology for UN Agencies.
I know market demand for multispectral imaginery and developed $100 spectroscope .
All I need is 10-band multispectral imaginery to study Urban Heat Island,
to study insolation level to develop solar farm for a given geolocation.
Just let me know why do you need 100-narrow-band multispectral imaginery or hyperspectroscopy ?
Following Vienna Conference I develop 100-DIY-seismograph network (DIY $100 seismograph for home use, to detect infrasounds transmitted through the ground, to detect vibrations from highway).
So I am flexible in cutting development costs.
I use drones to study solar farms for broken, faulty PV solar panels and
multispectral imaginery in basic mode works fine.
So I develop small r&d projects and my investment risk is contained
since I am not $$$ NASA.
If you can tell me why do you really need 100-narrow-band hyperspectral imaginery
(medicine - cancer detection???) so I will try to find a nice technology solution for you.
