DEVICE FOR CONTACTLESS DETERMINATION OF HEAT DIFFUSIVITY OF SOLID BODIES |
摘要 |
FIELD: physics.SUBSTANCE: device for contactless determination of heat diffusivity of solid bodies contains a flat optical heater and a thermal imager connected to a computer, optically opaque mask for formation of spatial heating field. The device also contains the optical lens intended for focusing of thermal radiation of the flat optical heater and optically opaque shutter allowing to open and close the thermal radiation of the flat optical heater in certain moments.EFFECT: improvement of accuracy of contactless determination of heat diffusivity of solid bodies.1 dwg |
