System for aligning a collimator and an alignment ring
Disclosed is a system for aligning a collimator tube with an alignment ring used to hold a film or sensor aligned with the collimator tube. The disclosed alignment system includes a light source, a light detector, and a reflective surface, where, when the collimator and alignment ring are aligned, light emitted from the light source reflects off the reflective surface and is received by the light detector.
1. A system for aligning a collimator and an alignment ring, the system comprising:
a light source;
a light detector;
a reflective surface, wherein the light source, the light detector and the reflective surface are constructed and arranged so that, when the collimator and alignment ring are aligned, light emitted from the light source reflects off the reflective surface and is received by the light detector; and
a magnetic sensor and a magnet, wherein the magnetic sensor detects when the magnet is in close proximity and wherein the magnetic sensor is coupled to the light source and light detector and activates the light source and light detector when the magnetic sensor detects that the magnet is in close proximity.
2. The system of claim 1 , wherein the light source emits a collimated beam of light.
3. The system of claim 1 , wherein the light source emits a laser light beam.
4. The system of claim 1 , wherein the light source and the light detector are affixed to the collimator and the reflective surface is affixed to the alignment ring.
5. The system of claim 1 , wherein, when the collimator and alignment ring are aligned and light emitted from the light source reflects off the reflective surface and is received by the light detector, the reflection angle of the reflected light is between approximately 10 degrees and approximately 170 degrees.
6. The system of claim 1 , wherein, when the collimator and alignment ring are aligned and light emitted from the light source reflects off the reflective surface and is received by the light detector, the reflection angle of the reflected light is an obtuse angle.
7. The system of claim 1 , wherein, when the collimator and alignment ring are aligned and light emitted from the light source reflects off the reflective surface and is received by the light detector, the reflective surface bisects the reflection angle of the reflected light in all planes.
8. The system of claim 1 , wherein the light source, the light detector and the reflective surface are constructed and arranged so that, when the collimator and alignment ring are misaligned, light emitted from the light source is not received by the light detector.
9. The system of claim 5 , wherein the light source, the light detector and the reflective surface are constructed and arranged so that, when the collimator and alignment ring are misaligned, light emitted from the light source is not received by the light detector.
10. The system of claim 3 , wherein the light source and the light detector are affixed to the collimator and the reflective surface is affixed to the alignment ring.
11. The system of claim 10 , wherein, when the collimator and alignment ring are aligned and light emitted from the light source reflects off the reflective surface and is received by the light detector, the reflection angle of the reflected light is between approximately 10 degrees and approximately 170 degrees.
12. The system of claim 10 , wherein, when the collimator and alignment ring are aligned and light emitted from the light source reflects off the reflective surface and is received by the light detector, the reflection angle of the reflected light is an obtuse angle.
13. The system of claim 10 , wherein, when the collimator and alignment ring are aligned and light emitted from the light source reflects off the reflective surface and is received by the light detector, the reflective surface bisects the reflection angle of the reflected light in all planes.
14. The system of claim 10 , wherein the light source, the light detector and the reflective surface are constructed and arranged so that, when the collimator and alignment ring are misaligned, light emitted from the light source is not received by the light detector.
15. The system of claim 12 , wherein the light source, the light detector and the reflective surface are constructed and arranged so that, when the collimator and alignment ring are misaligned, light emitted from the light source is not received by the light detector.
