Optoelectronic photodetector (variants)

摘要

A optoelectronic photo sensor to obtain single mosaic digital photographic images. Photo sensor is designed as a plurality of identical lenses having rows of staggered identical matrices arranged on a common focal surface with the gaps between adjacent matrices not exceeding the length of the effective number of pixels oriented along the row. Said arrangement provides a single large survey field from a plurality of individual matrices. Said design contemplates the use of several small individual lenses instead of one large and expensive lens, as well as many small matrices instead of one large and expensive matrix. The lenses are arranged at an angle to each other with a strictly defined dependence on the focal distance and the length of the gap between matrices in the row, which ensures continuous imaging by individual matrices over the surface surveyed with preset overlapping for subsequent cross-linking of images into one single film.

主权项

1. An optoelectronic photo sensor comprising an optic system and an electronic photosensitive device located on a focal surface thereof, wherein the optic system comprises at least two lenses, while the electronic photosensitive device comprises separate groups of identical digital photosensitive matrices corresponding to the number of lenses, wherein the total number of all matrices is no less than the number of lenses, wherein the matrices of each group are arranged in a row with gaps in between not exceeding, in size, the product of the number of effective pixels multiplied by a physical pixel size in one matrix along a symmetry axis, oriented along the row, multiplied by the number of groups minus one; wherein the groups of matrices are arranged in parallel rows with each on the focal surface of the corresponding lens in such a way that the matrices of one group are displaced with respect to the matrices of another group along a direction of their row to a distance not exceeding a length of a maximum gap between matrices in the row.
