Abstract:
The present invention relates to a microbolometer type vacuum sensor and an infrared sensor including the same and, more specifically, to a microbolometer type long-range vacuum sensor capable of accurately measuring a vacuum level in a wide vacuum level range and an infrared sensor including the same. The microbolometer type long-range vacuum sensor according to the present invention includes a substrate, and at least one first cell and at least one second cell which are arranged on the substrate and transfers electrical signals according to vacuum levels to the substrate. The microbolometer type long-range vacuum sensor according to the present invention can accurately measure a vacuum level in a wide range using together the first cell which has improved sensitivity at a low vacuum level and the second cell which has improved sensitivity at a high vacuum level.
