Abstract

An electromagnetic wave sensor comprises first wirings that extend in a first direction, second wirings that extend in a second direction, and bolometers. The thermal resistance of the second wiring per unit length in a direction of extension of the second wirings is lower than the thermal resistance of the first wirings per unit length in a direction of extension of the first wirings. One bolometer is physically connected to a first bolometer adjacent to the one bolometer in the first direction via one first wiring, physically connected to a second bolometer adjacent to the one bolometer in the second direction via one second wiring, and physically connected to the first bolometer via another second wiring adjacent to the one second wiring in the first direction.

Dependent claims

An electromagnetic wave sensor, comprising:

first wirings that extend in a first direction;
second wirings that extend in a second direction that is different from the first direction;
and
bolometers, wherein
thermal resistance of the second wirings per unit length in a direction of extension of the second wirings is lower than thermal resistance of the first wirings per unit length in a direction of extension of the first wirings,
the first wirings include one first wiring,
the second wirings include one second wiring and another second wiring adjacent to the one second wiring in the first direction,
the bolometers include one bolometer, a first bolometer adjacent to the one bolometer in the first direction, and a second bolometer adjacent to the one bolometer in the second direction, and
the one bolometer is physically connected to the first bolometer via the one first wiring, physically connected to the second bolometer via the one second wiring, and physically connected to the first bolometer via the another second wiring.
