- Abstract
- [ABSTRACT IN ENGLISH] Utilizing the characteristics of pyro-electrodes toward incident heat rays and electromotive forces an experimental model containing a scanning optical system was used to "chop" the heat ray to detect the position and spread of the fire. A fire-evaluating algorithm which detects increased irradiance and spread of combustion area was placed in the model tested.
