  • Patent number: 11789250
    Abstract: An optical detection device having a light detection device and a light emission device is arranged such that the light detection side of the light detection device is optically coupled to a light emission side of a light source array of the light emission device via an examination region. The light detection device generates an electrical signal n response to light that reaches the light detection side. The light source array includes a plurality of separately actuatable electric light sources which are arranged in a matrix structure or two dimensional geometric arrangement. The object to be examined can be arranged in a desired fashion, and the light emitted by the light sources radiates via the examination region on the light detection side of the light detection device. An optical reduction is system is arranged in the beam path from the light emission side to the examination region and is configured to demagnify the light pattern which is emitted by the light sources.
