Abstract
A boresight module includes a housing including an input window and an exit window. The boresight module further includes a lateral transfer hollow, dichroic beam splitter, retro-reflector (LTHSR) assembly supported by the housing. The LTHSR assembly includes a dichroic beam splitter. The boresight module further includes a corner cube coupled to the housing and a collimator including a collimator housing coupled to the housing and a target supported by the collimator housing. The target is configured to receive electromagnetic radiation from the input window to emit electromagnetic radiation through the exit window. A method of aligning a device with a boresight alignment module is further disclosed.
Claims8
A method of aligning a device with a boresight alignment module, the method comprising:
- receiving incoming electromagnetic radiation through an input window of a lateral transfer hollow, dichroic beam splitter, retro-reflector (LTHSR) housing;
- transmitting part of the incoming electromagnetic radiation through a dichroic beam splitter having a first side and a second side;
- reflecting the transmitted part of the incoming electromagnetic radiation off of a corner cube;
- reflecting the incoming electromagnetic radiation from the corner cube off of the second side of the dichroic beam splitter and into a collimator;
- focusing the incoming electromagnetic radiation on a target by the collimator;
- emitting outgoing electromagnetic radiation by the target in response to the incoming electromagnetic radiation;
- transmitting part of the outgoing electromagnetic radiation through the dichroic beam splitter;
- and
- receiving the transmitted part of the outgoing electromagnetic radiation by one of the plurality of sensors,
- wherein the dichroic beam splitter has one highly-transmissive (HT) surface in all wavelengths and one surface with a 50/50 transmission/reflection for a laser wavelength.
