Zusammenfassung: | A light detection device 1 includes a light detection unit 20. The light detection unit 20 includes an APD 11, a plurality of temperature compensation diodes 16a, 16b, 17a, and 17b, and a terminal 22 electrically connecting the APD 11 and the plurality of temperature compensation diodes 16a, 16b, 17a, and 17b in parallel with each other. The plurality of temperature compensation diodes 16a, 16b, 17a, and 17b is configured to provide temperature compensation for the gain of the APD 11. The light detection unit 20 has a light detection region 71 and temperature detection regions 72 and 73. The APD 11 is provided in the light detection region 71. The temperature detection regions 72 and 73 are located around the light detection region 71. The plurality of temperature compensation diodes 16a, 16b, 17a, and 17b are provided in the temperature detection regions 72 and 73. The light detection region 71 is interposed between the temperature detection region 72 and the temperature detection region 73. |
