Abstract:
An apparatus for testing at least one dynamic optical component of at least one optical head, comprising:a source of light, said source of light providing a light along an optical path;a mount;at least one detector coupled to said mount for detecting said light; andprocessing circuitry, said at least one detector coupled to said processing circuitry for detecting said light and providing an output representative of a characteristic of said at least one dynamic optical component; wherein said processing circuitry processes said output and provides a result based on said output; wherein said at least one dynamic optical component comprises a steerable micro-machined reflector, wherein said steerable micro-machined reflector alters said optical path of said light, and wherein said at least one detector is disposed in said optical path of said light opposite said steerable micro-machined reflector.
