Abstract

PURPOSE:To display a distinct image by arranging each element arrangement corresponding to aberration of a lens to cancel the aberration of the lens. CONSTITUTION:The element 2, 5 at a luminescence or a photodetecting face of a light emitting element group 1 or a photodetector group 4 are arranged before and after the lens in the direction of optical axis and the arrangement is set in correspondence to the aberration of the lens of a lens system 3 or 6. Since distortion due to the aberration of the lens causes a biased focus in the optical axis direction, a distinct image immune to the aberration of lens is obtained by corresponding the arrangement of the elements 2, 5 to the distortion.
