Abstract[English]
Aspects of the present disclosure provide techniques for performing a safety test of a laser diode associated with an ophthalmic surgical apparatus. An example method determining a measured slope efficiency of the laser diode based on a plurality of different current levels applied to an input of the laser diode and a plurality of different output power levels associated with the laser diode, determining an expected slope efficiency of the laser diode based on a measured operating temperature of the ophthalmic surgical apparatus, determining a result of the safety test of the laser diode based on the measured slope efficiency of the laser diode and the expected slope efficiency for the laser diode, and outputting an electrical signal indicating a result of the safety test of the laser diode.[French]
Des aspects de la présente divulgation concernent des techniques pour effectuer un test de sécurité d'une diode laser associée à un appareil chirurgical ophtalmique. Un procédé donné à titre d'exemple détermine une efficacité de pente mesurée de la diode laser sur la base d'une pluralité de niveaux de courant différents appliqués à une entrée de la diode laser et d'une pluralité de niveaux de puissance de sortie différents associés à la diode laser, détermine une efficacité de pente attendue de la diode laser sur la base d'une température de fonctionnement mesurée de l'appareil chirurgical ophtalmique, détermine un résultat du test de sécurité de la diode laser sur la base de l'efficacité de pente mesurée de la diode laser et de l'efficacité de pente attendue pour la diode laser et délivre un signal électrique indiquant un résultat du test de sécurité de la diode laser.
