Abstract
A multispectral or thermal imager comprising a lens assembly, an array of IC chips that is arranged in a field of view of the lens assembly, and a filter assembly comprising one or more wavelength filters. The filter assembly comprises a respective wavelength filter for at least one of the three or more rows of IC chips. At least one wavelength filter is transparent in a portion of a wavelength range that passes through the lens assembly. The filter assembly is configured such that radiation of the same wavelength range passes to the rows of IC chips in the pair of non-adjacent rows, and such that the wavelength range that passes to the rows in the pair of non-adjacent rows is different from a wavelength range that passes to the one or more rows other than the pair of non-adjacent rows.
Claims20
A thermal imager, comprising:
- a lens assembly;
- an array of integrated circuit (IC) chips that is arranged in a field of view of the lens assembly;
- and
- a filter assembly comprising one or more wavelength filters,
- wherein the IC chips are arranged in three or more parallel rows of IC chips that include a pair of non-adjacent rows of IC chips and one or more rows of IC chips other than the pair of non-adjacent rows of IC chips;
- wherein the filter assembly is arranged between the array of IC chips and the lens assembly and comprises a respective wavelength filter for at least one of the three or more rows of IC chips, wherein the respective wavelength filter is transparent in a portion of a wavelength range of radiation that can pass through the lens assembly;
- and
- wherein the filter assembly is further configured such that radiation of the same wavelength range can pass to the rows of IC chips in the pair of non-adjacent rows of IC chips, and such that the wavelength range of radiation that can pass to the rows of IC chips in the pair of non-adjacent rows of IC chips is different from a wavelength range of radiation that can pass to the one or more rows of IC chips other than the pair of non-adjacent rows of IC chips.
A thermal imager, comprising:
- an image sensor including an array of integrated circuit (IC) chips arranged in three or more parallel rows of IC chips;
- and
- a filter assembly comprised of one or more wavelength filters,
- wherein:
- the array of IC chips includes a pair of non-adjacent rows of IC chips and one or more rows of IC chips other than the pair of non-adjacent rows of IC chips;
- and
- the filter assembly is configured such that radiation of a first wavelength range can pass through the filter assembly to the pair of non-adjacent rows of IC chips, and radiation of a second wavelength range can pass through the filter assembly to the one or more rows of IC chips other than the pair of non-adjacent rows of IC chips, wherein the second wavelength range is different from the first wavelength range.
