  • Publication number: 20220326085
    Abstract: An infrared sensor uses an infrared lens with infrared filtering and focusing functions. Thus, an infrared filter can be omitted to reduce the costs and volume. In addition, a getter on the inside of a metal cover of the infrared sensor can be activated when the metal cover is soldered to the substrate of the infrared sensor. Therefore, the packaging process of the infrared sensor can be simplified.

  • Patent number: 10006983
    Abstract: A method for detecting azimuthal angle of a heat source includes a preparing step and a detecting step. The preparing step includes: detecting a unit period (Tc) by rotating a target positioning portion through one circle, and aligning the target positioning portion with an aligning member. The detecting step includes: driving the target positioning portion to rotate. The position of the aligning member defines an initial azimuthal position. When an infrared signal emitted from the external heat source is transmitted into an infrared sensor via the target positioning portion, a transmitting time is defined as a time point (Ts) of the heat source, and an angle between the target positioning portion and the initial azimuthal position is defined as an azimuthal angle (?x) of the heat source, in which ?x=(Ts/Tc)×360°.
