Hello,
Maybe there is among us some observers of UFOs. In that case it could be useful to acquire a diffraction grating.
It is expected among others by Jean-Pierre PETIT, a french physicist, a bit "off limits".
This can be placed in front of the objective of the device. It diffracts the light and permits to analyse the light emitted.
The phenomenon can be then associated with the type of the physical source.
I did not find photos taken with grating, though usefull to study the UFO phenomenon.
In France, the Gendarmerie was equipped, but not used it :

OPTICAL DIFFRACTION GRATING CAMERA CAPS
An another topic, "diffracting camera caps" were distributed to the French national military police squads "Gendarmerie" in the 1980's. Made of an optical diffraction grating pattern conceived by Jobin & Yvon company, they can be fixed in front of the camera's objective glass to print on the film the spectral lines of any luminous object, transforming the camera into a true spectroscope.
Diffraction gratingThe French Gendarmes had the role of using them each time they would observe unidentified luminous phenomena at night. These diffracting caps were made in order to know more about UFOs, because the luminous spectrum of an object gives information on its chemical composition, its temperature, if it emits characteristic radiations such as infrareds or ultraviolet rays, if it generates a magnetic field, high-frequencies, etc.
After thirty years, what are the results, according to consultants of the laboratory charged to analyze these spectra? Two pictures, and none is exploitable! Besides these caps are lost since a score of years at the bottom of forgotten drawers. Now people have a lot of digital cameras even in their mobile phone, so it would be interesting to equip the general public with these cheap diffracting caps.
All these alleged official studies wasting public monies without any result must be stopped and replaced by another functional approach. It is not even the problem "to convince the authorities" any more. Simply a real serious and profitable scientific study can and will now be undertaken.
