Abstract

L'invention concerne un procédé et un appareil de commande de puissance d'émission, un support de mémoire et un dispositif électronique, dans lesquels ceux-ci se rapportent au domaine de la détection d'une substance, sont appliqués à un appareil de détection, et sont caractérisés en ce que : l'appareil de détection comprend : un capteur de température et un émetteur laser. Le procédé comprend les étapes suivantes : lorsqu'une substance à détecter est détectée, acquérir des informations de variation de température de la substance, qui doivent être détectées, en fonction de la température, collectée par un capteur de température, de la substance à détecter, et commander la puissance d'émission de l'émetteur laser en fonction des informations de variation de température. Sous la prémisse de garantir l'efficacité de détection d'une substance, la puissance d'émission de l'émetteur laser peut être commandée de manière rationnelle, l'intégrité de la substance à détecter peut être protégée, et la sécurité de l'appareil de détection peut être améliorée.
