A fast optical pyrometer is described ; its rise time is about 50 ns ; it gives for a 4 mm2 surface at a temperature higher than 1 700 K, four brightness temperature in the visible and in the near infrared. This pyrometer has been used to measure the temperature of a graphite sample and of the detonation products of a liquid explosive.Description d'un pyromètre optique au temps de montée de l'ordre de 50 nanosecondes et permettant la mesure de 4 températures de luminance, dans le visible et le proche infrarouge, d'une surface de 4 mm 2 et de température supérieure à 1 700 K. Le pyromètre est utilisé, à titre d'exemple, pour mesurer la température d'un élément de graphite puis celle des produits de détonation d'un explosif liquide
