Description
Technical field
The present invention relates to a kind of device that utilizes paraboloidal mirror to transmit luminous energy, this device utilizes paraboloidal mirror special ray reflecting characteristics, make the parallel rays of this device of incident be converged effectively or disperse, thereby realize multiple different practical application, belong to the optical devices technologies field.
Background technology
Only a kind of electromagnetic radiation can be regarded as light wave or photon; As differentiation, then can be divided into visible light and invisible light with the mankind's visual capacity, the electromagnetic radiation of every high frequency all has the physical features identical with visible light, can be considered as a kind of light source.Sunshine, moonlight, starlight, artificial laser, other artificial light sources, visible light, invisible light, electromagnetic radiation all are a kind of light sources.Converge the technology of light source at present, mainly be divided into following three kinds of schemes:
(1) be to use convex lens: this convex lens are popular to know that it can be with light-ray condensing on focus.Utilize the light that converges of this lens after leaving focus, can spread out, can't be sent at a distance converging later light.
(2) be to use Fresnel Lenses (Fresnel lens): present Fresnel Lenses major part is to be annotated by polyolefine material to press the thin slice that forms, also have and make by glass, lens surface simultaneously is the light face, the another side imprinting ascending concentric circles, its texture utilizes interference of light and disturbs and penetrate and require to design according to relative sensitivity and receiving angle, the requirement of lens is very high, the lens of a slice high-quality must be any surface finish, clean mark, its thickness becomes with purposes, how about 1mm, characteristic is that area is bigger, thin thickness and detecting distance.
Fresnel Lenses be equivalent to convex lens many times, effect is better, but cost is more much lower than common convex lens.Be used for accuracy requirement is not very high occasion more, as slide projector, film magnifier, infrared eye etc.The Fresnel Lenses effect has two: the one, and focussing force, be about to heat and release infrared signal refraction (or reflection) on PIR (passive infrared line detector), second effect is to release infrared signal be divided into several area pellucidas and dark space in the search coverage, make the mobile object that the enters search coverage heat that can change with the form of temperature variation on PIR.
This lens have many processing and manufacturing schemes, and publication number is a kind of process technology scheme that the Chinese patent of CN1431526 just once disclosed this lens.Can't being sent at a distance that the light source that this lens compile is same is used.
(3) be to use parabolic reflector: the reflecting surface of this catoptron is the para-curve surface of revolution, cylindro-parabolic, ring-type parabola.Para-curve surface of revolution catoptron can make light at a distance collect in its focus place, becomes circular hot spot; This parabolic reflector is used in solar electrical energy generation at present.The cylindro-parabolic catoptron can make light at a distance compile the hot spot that becomes strip; This parabolic reflector is used in solar groove type generating or heating system at present.The ring-type parabolic mirror can make light at a distance compile the hot spot that becomes ring-type, the present less utilization of this parabolic reflector.Same, the light after converging will scatter after in a single day leaving focus, still can't be sent at a distance to be used.
Transmit the most easy method of light at present and utilize a catoptron exactly, use manual or mechanical control to adjust the direction and the elevation angle, just can reflex on the target object of distant place from the light that shines in the distant place on the minute surface.Utilize a plurality of catoptrons just can make light directly arrive at target along winding raod.This scheme can be implemented in the space more than the face of land arbitrarily, also can implement in the pipeline of a sealing.
The another kind of method that transmits light is utilized optical fiber or optical cable exactly.Certainly, we also can plate high reflecting material with a pipe interior, for example silver or aluminium, make light within it portion transmit along with the pipeline of complications.This pipe interior is vacuum state preferably, and at reflection spot installing cooling device.
Also having a kind of method of transmitting light is exactly to utilize above-mentioned Fresnel Lenses (Fresnellens), place light indoor light source, has the dress Fresnel Lenses all around, the effect of the light process Fresnel Lenses that light is indoor becomes intimate parallel light beam, can shine 20 miles even farther place, the beacon on seashore or the reef utilizes this technology exactly at present.
Come in order to make light can be sent to be unlikely to scatter at a distance, light beam must be a parallel beam.Starlight, moonlight, sunshine at a distance can be considered as a kind of parallel beam.Artificial laser (radium-shine laser) also is a kind of parallel beam, and it can be sent to and can not disperse at a distance, has therefore all obtained using widely aspect many at communication, industry, weapon and other.Yet laser is artificial expensive light source, and up to this point still can't produce the powerful generating laser of power.
