[0028] The present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings.
[0029] In this embodiment, a large field of view linear infrared detector is provided, and its structure is as follows: Figure 2-9 As shown, it includes a spherical package cap 1, a curved surface flexible sensitive circuit 2, a PCB board 3, and a package base 4; wherein, the spherical optical filter 1-1 is embedded on the spherical package cap shell 1-2 through a curved surface window to form a spherical package cap 1. The curved surface flexible sensitive circuit 2 includes a copper wire 2-1, a composite film sensitive layer 2-2, and a PET / PI flexible substrate 2-3. On the copper wire 2-1 on the PET / PI flexible substrate 2-3, they are electrically connected; the weak electrical signal generated by the composite film sensitive layer 2-2 is conducted to the PCB through the copper wire 2-1 The cable socket 3-2 on the board 3, the signal is co...
