Abstract
An optical image recording device comprises a housing having a comparatively small height and at least one comparatively broad optical image information entering surface, an optical path unit including a first lens array, a second lens array and an optical image recording device including an image sensor, while in the optical path unit the first lens array is guiding the entering optical information to the optical axis of the second lens array extending substantially perpendicular to the height of the housing and the optical image information is received by the image sensor, and the optical image recording device further including electrical circuitry coupled to the image sensor for processing and storing the image data.

An optical image recording device comprising
- a housing having a comparatively small height and at least one comparatively broad optical image information entering surface,
- an optical path unit including a light guiding element, an image forming lens array and an optical image recording device including an image sensor, while in the optical path unit the light guiding element is guiding the entering optical information to the optical axis of the image forming lens array extending substantially perpendicular to the height of the housing and the optical image information is received by the image sensor through the image forming lens array, and
- the optical image recording device further including electrical means coupled to the image sensor for processing and storing the image data,
- characterised in that at least two different optical path units are comprised, each of which is processing and recording at least a respective part of the entering optical information, and that combining means are provided in the optical image recording device for electrically combining the signals recorded in the respective optical image recording devices;
- wherein said at least two different optical path units comprise a first optical path unit and a second optical path unit, wherein
- the first optical path unit comprises a first image sensor, a first image forming lens array and a first light guiding element for guiding the perspective part of the entering optical information through the first image forming lens array to the first image sensor;
- the second optical path unit comprises a second image sensor, a second image forming lens array and a second light guiding element for guiding the perspective part of the entering optical information through the second image forming lens array to the second image sensor, wherein
- the first image forming lens array has an optical axis substantially perpendicular to the height to the housing and
- the second image forming lens array has an optical axis substantially perpendicular to the height to the housing, and wherein the first optical path unit and the second optical path unit are arranged such that the first image forming lens array and the second image forming lens array are located between the first image sensor and the second image sensor.
