    Default Making laser detector

    In french:

    Je veux fabriquer un antilaser comme celui qu' il y a dans ce site : www.antilaser.com , le problème avec les pistolets laser c'est qu'ils calculent les vitesses en 0,5s donc le but de ce circuit est de detecter le laser et de le brouiller pendant quelques secondes le temps de ralentir. Je pense que c'est pas trop compliquer a faire:

    -Sachant que les pistolers laser emmettent en 904nm il faut une ou plusieurs photodiodes SFH2030 ou SFH320FAZ pour detecter le faiseau laser

    -Une ou plusieurs diodes laser 904 nm,une référence: 25 W / 905 nm,SPLPL90

    Toutes les references sont disponibles sur www.radiospares.com

    j'ai trouvé ce schema interresant a vous de l'améliorer,experts en electronique, et de poster vos changements. Merci:

    Une fois un laser detecté il faut creer un temporiseur pour que la diode laser arrete d'emettre au bout de 5sec sinon ont est detecté par le pistolet affiche "JAMMED"
    Il faut aussi une ou deux diodes et un buzzer pour prevenir le conducteur.

    I think that is not too much to complicate has to make:

    - Knowing that the pistolers laser emmettent in 904nm one needs one or more photodiodes SFH2030 or SFH320FAZ for detecter the laser faiseau

    -One or more lasers diode 904 Nm, a reference: 25 W/905 Nm, SPLPL90

    once a detecté laser it is necessary for to creer a temporisor so that the laser diode arrete to emit at the end of 5sec if not have is detecté by the gun posts "JAMMED" One needs also one or two diodes and a buzzer to prevenir the driver.

    I have not looked at phototransistors, but some of the commercial detectors use SFH-203 series photodiode made by Siemens.

    You are correct sir.

    Made by Osram.

    They are also the people who make the SPL_PL90 laser diodes used in range finding. Same variation as used on the LRC100 and Defender2.
