The invention discloses a full-light information collection system. Specifically, the system is characterized in that a spectrum image of sparse sampling is obtained by a sparse sample imaging array, a light splitting device, a gray scale imaging device and a spectrum light path collection device; a color image with high resolution is obtained by a color imaging device and a color light path collection device; light axes of the spectrum light path collection device and the color imaging device are parallel, the obtained two images respectively includes spectrum information of the sparse sampling and color information of the high resolution, and the obtained two images includes parallax information; finally, the two paths of information are processed by an information combined processing device, full-light information including a spectrum and a depth is reestablished according to the sparse spectrum information, the color information and the parallax information due to different poses of two cameras. According to the invention, the combined obtaining of the full light information is realized, and the higher spectrum resolution and the more precise depth information can be obtained by adopting the imaging device higher in precision.

The invention discloses a linear gradual filter type multispectral imager based on secondary imaging. The linear gradual filter type multispectral imager based on secondary imaging comprises a front imaging system, a linear gradual filter, a transmission type relay imaging objective lens and a detector, wherein the front imaging system, the linear gradual filter, the transmission type relay imaging objective lens and the detector are arranged in sequence. The front imaging system is used for imaging an object. The linear gradual filter is arranged on an instant image surface of the front imaging system and used for achieving spectral division of a space object. The transmission type relay imaging objective lens is used for imaging the instant image surface subjected to spectral division onto the detector again. The detector obtains and records digital information through the photoelectric effect. The distance between the linear gradual filter and the front imaging system and the distance between the linear gradual filter and the transmission type relay imaging objective lens are not smaller than a preset value. By the adoption of the multispectral imager, influences of spectrum aliasing on the spectral resolution can be completely eliminated, and meanwhile forming of a ghost image is avoided.
