Abstract: An image acquisition system is disclosed. The image acquisition system includes: an object area configured to form an image on an image side; a condenser lens configured to converge light from the object area, the condenser lens being located on a light path of the object area; a color filter configured to filter the light collected by the condenser lens to obtain single wavelength of light, according to a forward direction of the light, the color filter being placed in front of the condenser lens; and an image sensor configured to receive the image on an imaging plane position of an image space, the image sensor being placed in front of the imaging plane position according to the forward direction of the light. The matrix image acquisition system and the matrix image projection system including the image acquisition system are also disclosed.

Abstract: The present disclosure relates to a matrix optical system, a light ray condensing system and a compound eye lens. The matrix optical system includes a first lens and a second lens. The first lens includes a plurality of first lens units, focal lengths of the plurality of first lens units are different. The second lens includes a plurality of second lens units, focal lengths of the plurality of the second lens units are different. A distance of the plurality of first lens units is different from a distance of the plurality of second lens units. The first lens and the second lens are arranged in parallel and spaced apart. A light ray condensing system and a compound eye lens including the matrix optical system are further provided.
