摘要： In at least one embodiment, an infrared (IR) sensor comprising a thermopile is provided. The thermopile comprises a substrate and an absorber. The absorber is positioned above the substrate and a gap is formed between the absorber and the substrate. The absorber receives IR from a scene and generates an electrical output indicative of a temperature of the scene. The absorber is formed of a super lattice quantum well structure such that the absorber is thermally isolated from the substrate. In another embodiment, a method for forming an infrared (IR) detector is provided. The method comprises forming a substrate and forming an absorber with a plurality of alternating first and second layers with a super lattice quantum well structure. The method further comprises positioning the absorber about the substrate such that a gap is formed to cause the absorber to be suspended about the substrate.

摘要： An infrared (IR) detector including a plurality of thermal sensing elements for generating an image of an object is provided. The IR detector comprises a first thermal sensing element and includes a thermopile and a first switch. The thermopile is configured to receive at least a portion of a thermal output from the object and to provide a modulated electrical output indicative of at least a portion of the received thermal output. The first switch is operatively coupled to the thermopile and is configured to provide a bypass in the event the thermopile is damaged such that remaining thermal sensing elements of the plurality of thermal sensing elements are capable of providing an electrical output therefrom.

摘要： In an optical element, diffractive focusing features and diffractive anti-reflection features can extend into a first surface of a body, such as by etching. The diffractive focusing features can have a same first depth that is greater than a wavelength, and can be located in a first area to have a duty cycle that varies over the first area. The diffractive anti-reflection features can have a same second depth that is less than the wavelength. In some examples, an effective refractive index of the diffractive focusing features and the diffractive anti-reflection features, together, can be less than or equal to a specified value, such as 120% of a square root of a refractive index of a material of the body. In other examples, the diffractive anti-reflection features can be located in the first area to have a duty cycle that is constant over the first area.
