Abstract

A stereoscopic camera for recording the surroundings is provided with a right and a left image sensor having one lens each to display the surroundings on the image sensors, with the image sensors and the lenses being held by a carrier side-by-side and at a distance in reference to each other. The stereoscopic camera is additionally provided with a circuit board arranged on the carrier and comprising at least the signal and the supply lines of both image sensors. The image sensors are each mounted on a carrier substrate, which similar to the lenses, are arranged on the carrier and are distanced in reference to the circuit board, and have a flexible electric connection to the circuit board.

Claims

1. A stereoscopic camera for recording surroundings, comprising a right image sensor and a left image sensor, a lens associated with each image sensor to display the surroundings on the image sensors, with the image sensors being held next to each other and at a distance in reference to each other by a carrier, and with a circuit board arranged on the carrier and at least provided with signaling and supply lines for both image sensors, wherein each image sensor is mounted on a separate carrier substrate, the lenses and both carrier substrates are arranged on the carrier and distanced from the circuit board, and the image sensors are connected to the signaling and supply lines via flexible connections.

2. A stereoscopic camera according to claim 1, further comprising a lens fastener for at least one lens, said at least one lens being made from an optically dense material, and wherein the at least one lens together with the carrier forms a hollow space around one image sensor by the lens fastener being mounted optically dense on the carrier.

3. A stereoscopic camera according to claim 2, wherein the lens fastener has supports by which the lens fastener rests on the carrier so that a joint develops between the lens fastener and the carrier, the joint being closed by a flexible and optically dense joint material.

4. A stereoscopic camera according to claim 2, wherein the lens fastener has a penetration, through which the circuit board reaches into the hollow space so that a joint develops between the lens fastener and the circuit board and the joint is closed with a flexible and optically dense joint material.

5. A stereoscopic camera according to claim 3, wherein the joint material comprises silicon.

6. A stereoscopic camera according to claim 2, wherein the lens fastener has a fastening means extending in a recess in the carrier, with a cross-section of the fastening means parallel to a base of the recess increasing towards the base, the fastening means extending so far into the recess of the carrier that a clear space develops between a base of the fastening means and the base of the recess, and a space of the recess surrounding the fastening means including said clear space is filled with a hardening material.

7. A stereoscopic camera according to claim 1, wherein a focus of the lens is adjustable.

8. A stereoscopic camera according to claim 1, wherein the image sensors are inside a housing.

9. A stereoscopic camera according to claim 1, wherein the carrier is made from metal.
