Abstract
Inventia se refera la o metoda pentru transmiterea de informatii în spatiul liber prin intermediul unor unde electromagnetice, precum si l a un echipament pentru aplicarea acestei metode. Metoda, conform inventiei, consta în aceea ca, dinspre partea de emisie înspre partea de receptie sunt astfel orientate cel putin doua fascicule de raze modulate coerent cu o distanta dintre axele radiatiilor de cel putin 200 mm si de cel putin 100 lambda, încât fasciculele de raze se intersecteaza de partea receptiei, precum si în aceea ca de partea receptiei se detecteaza intensitatea comuna a fasciculelor de raze care se intersecteaza si informatia este reprodusa din semnalul care rezulta din detectare. Echipamentul care serveste la aplicarea metodei, conform inventiei, este caracterizat prin aceea ca de partea emisiei la un modulator sunt racordate cel putin doua emitatoare aflate la o distanta de cel putin 200 mm si de cel putin 100 lambda între ele si prevazute cu un dispozitiv de formare a fasciculelor, lambda fiind lungimea de unda a undei electromagnetice folosite.
