Abstract
A multiple image camera for measuring the alignment of objects in different planes. The camera includes two coupled imaging devices configured to directly image objects in different planes without any intervening reflective optics between the imaging devices and the objects. The camera thus allows measurement of the alignment between the first and second objects without the need for repeated calibration between the image from the two imaging devices.

A multiple image camera for measuring an alignment of objects in different planes, comprising:
- a first CCD imaging device with a first focusing lens, the first imaging device configured to directly image a first object through the first lens along a first imaging axis, without any intervening reflective optics between the first imaging device and the first object;
- and
- a second CCD imaging device with a second focusing lens, the second imaging device configured to directly image a second object through the second lens along a second imaging axis, without any intervening reflective optics between the second imaging device and the second object;
- whereby the first and second imaging devices are fixed relative to one another, and are directly or indirectly mounted on opposite sides of a flat electronic component carrier, to allow measurement of the alignment between the first and second objects without a need for repeated calibration between the images from the two imaging devices.
A multiple image camera for measuring the alignment of objects in different planes, comprising:
- a printed circuit board defining parallel faces;
- a first CCD mounted to a first face of the printed circuit board;
- a first lens directly over the first CCD, above the first face of the circuit board, for focusing light onto the first CCD;
- a first lens housing coupled to the first face of the circuit board, and holding the first lens relative to the first CCD;
- a second CCD mounted to a second face of the printed circuit board;
- a second lens directly over the second CCD, above the second face of the circuit board, for focusing light onto the second CCD;
- and
- a second lens housing coupled to the second face of the circuit board, and holding the second lens relative to the second CCD.
A multiple image camera for measuring the alignment of objects in different planes, comprising:
- a printed circuit board defining parallel faces;
- a first CCD mounted to a first face of the printed circuit board;
- a first lens directly over the first CCD, above the first face of the circuit board, for focusing light onto the first CCD;
- a first lens housing coupled to the first face of the circuit board and surrounding the first CCD, and holding the first lens relative to the first CCD;
- a light-blocking seal at a junction of the first lens housing and the first face of the circuit board, to prevent ambient light from entering the first lens housing, except through the first lens;
- a second CCD mounted to a second face of the printed circuit board;
- a second lens directly over the second CCD, above the second face of the circuit board, for focusing light onto the second CCD;
- a second lens housing coupled to the second face of the circuit board and surrounding the second CCD, and holding the second lens relative to the second CCD;
- a light-blocking seal at a junction of the second lens housing and the second face of the circuit board, to prevent ambient light from entering the second lens housing, except through the second lens.
