Definitions
- the reticle holder blade in a viewfinder or in binoculars
- the detector surface in a camera or a camera, whether film or digital. It is also the retina of the eye.
- Such a surface absorbs or transmits part of the energy to form the useful signal, for example that of a photographic image, a video signal or a retinal image and reflects another specularly or diffusely. incident energy. This energy is partly collected by the optics of image formation which, according to the principle of the reverse return of the light, returns it in a very directive way in the plane of the source where it is concentrated.
- Another observation instrument is located in the immediate vicinity of the luminous object, also called the source, or is virtually superimposed on it by optical means, it receives this concentrated flux coming from the first observation system.
- the object is an intense light source (a laser in particular)
- the beam concentrated in return can create on this second observation system an image of the first much brighter than its environment.
- the definition of the laser equivalent surface is more general but we are only interested here in the mono static Laser Equivalent Surface (SEL). In the latter the laser emitter and the detector which receives the reflected light are close enough to be considered as confused when they are seen from the first observation system.
- SEL Laser Equivalent Surface
- the objective is fixed and it comprises means for adjusting the position of the mirror which are capable of adjusting the distance separating the objective from the mirror.
- the mirror is fixed and it comprises means for adjusting the position of the objective which are capable of adjusting the distance separating the objective from the mirror.
- said mirror is a plane mirror and is preferably arranged perpendicularly to said optical axis of the device so that most of the incident light is returned towards the objective.
- a device according to the invention comprises alignment means capable of aligning it with a second device, such as an external active detection device, so as to make this second device collinear with the optical axis
- alignment means may include sighting means, for example constituted by a sighting scope or a handlebar and an eyepiece.
- the sighting means can be arranged laterally with respect to the optical axis and means for obscuring the sighting means can be provided so that the latter do not modify the laser equivalent surface of the device according to the invention.
- FIG. 1 shows schematically the general means of an alternative embodiment of the invention.
- the support structure 12 comprises a rail 13 which constitutes the frame of the entire device. Jumpers 14 make it possible to fix, on the rail 13, the doublet objective of 200 mm focal length 2, the attenuating filter 8, the means 5 capable of adjusting the position of the mirror 3 along said optical axis OZ, and the means of aim 11.
- a jumper forming an adapter plate of the mounting 15 has a tapped hole which makes it possible to fix the assembly on a stand for a camera.
- a shutter flap 16 is disposed in front of the sighting means 11. It can take two positions: the first in which it is outside the sighting axis
- All the sighting means can be used.
- the latter having its own laser equivalent surface poorly controlled, must be able to be obscured when the instrument is used so as not to add its laser equivalent surface to that of the instrument. If it is, as on a rifle, a handlebar and an eyecup; it then has a negligible laser equivalent surface.
- the user only has to fix the assembly on a photo stand at the level of the adapter plate 15, adjust the orientation by means of the photo stand using the telescopic sight 11, the shutter flap 16 being open , then close the blacking shutter 16 and adjust the position of the plate 9, by simply rotating the knurled control button 10, to the value read on the charts.
