System and method for x-ray compatible 2D streak camera for a snapshot multiframe imager
The present disclosure is directed to a snapshot multiframe imager having an aperture element having at least one aperture, an adjacently positioned random mask, an imaging element and a computer. The random mask has a plurality of micron scale apertures and receives light passing through the aperture element, which represents the spatial information from the scene being imaged, and generates a plurality of image frames encoded in a spatial domain. The imaging element may operate in a drift-scan mode receives the encoded image frames and generates a streaked pattern of electrons representing a plurality of images of the scene at a plurality of different times. The computer analyzes the streaked pattern of electrons and mathematically reconstructs the plurality of images.
IMAGING UNIT, IMAGING APPARATUS, AND COMPUTER READABLE MEDIUM STORING THEREON AN IMAGING CONTROL PROGRAM
When the amplification ratio is low and strong incident light causes a large charge, the signal retrieved from regions where the incident light is weak is also weak, but when the amplification ratio is high in regions where the incident light is weak, the signal retrieved from regions where the incident light is strong becomes saturated. Therefore, the dynamic range of the imaging unit is narrow. Provided is an imaging unit comprising an imaging section that includes a first group having one or more pixels and a second group having one or more pixels different from those of the first group; and a control section that, while a single charge accumulation is performed in the first group, causes pixel signals to be output by performing charge accumulation in the second group a number of times differing from a number of times charge accumulation is performed in the first group.

A polarization imaging section 20 includes polarized pixels in each of a plurality of polarization directions. The polarization imaging section 20 includes a polarizer. The polarization imaging section 20 outputs image signals of a polarized image to a defect detecting section 35 of an image processing section 30. In a case where a difference between a pixel value of a target polarized pixel generated by the polarization imaging section and a pixel value of the target polarized pixel estimated from polarization characteristics corresponding to pixel values of peripheral pixels in a polarization direction different from a polarization direction of the target polarized pixel is greater than a predetermined allowable range, the defect detecting section 35 determines that the target polarized pixel is a defective pixel. Therefore, it is possible to detect a defect of a pixel in the polarization imaging section that generates the polarized image.
