Abstract
An accurate temperature measurement structure of a wide temperature range includes: a lens set; an optical base, having a neutral density slot and being fixed with the lens set by a first screw; a mask shutter assembly, fixed with the optical base by a second screw; and a temperature sensing unit, for sensing a target object temperature so as to obtain a measured temperature value, the temperature sensing unit performing a temperature normalization correction when the accurate temperature measurement structure of the wide temperature range is in a power-on stage to obtain a signal strength value, setting a plurality of signal conditions according to the signal strength value to obtain a dynamic linearity strength value and accordingly determining an extreme value region, so as to determine whether to add a neutral density filter to the neutral density slot.
