Electromagnetic radiation steering mechanism

An electromagnetic radiation detector comprising:

• an electromagnetic radiation steering mechanism configured to steer electromagnetic radiation to address a specific location within a two-dimensional field of view, wherein the electromagnetic radiation steering mechanism comprises,
• a first optical element having an associated first actuator configured to rotate the first optical element about a first rotational axis to change a first coordinate of a first steering axis in the two-dimensional field of view;
• a second optical element having an associated second actuator configured to rotate the second optical element about a second rotational axis to change a second coordinate of a second steering axis in the two-dimensional field of view;
• and
• an electromagnetic radiation manipulator optically disposed between the first and second optical elements, wherein
• a first angle is defined between the first and second rotational axes;
• a second angle is defined between the first and second steering axes;
• and,
• the electromagnetic radiation manipulator is configured to introduce a difference between the first angle and the second angle, wherein the electromagnetic radiation manipulator comprises a first mirror and a second mirror that are non-rotatable with respect to each other.

An optical scanner comprising:

• an electromagnetic radiation steering mechanism configured to steer electromagnetic radiation to address a specific location within a two-dimensional field of view, wherein the electromagnetic radiation steering mechanism comprises,
• a first optical element having an associated first actuator configured to rotate the first optical element about a first rotational axis to change a first coordinate of a first steering axis in the two-dimensional field of view;
• a second optical element having an associated second actuator configured to rotate the second optical element about a second rotational axis to change a second coordinate of a second steering axis in the two-dimensional field of view;
• and
• an electromagnetic radiation manipulator optically disposed between the first and second optical elements, wherein
• a first angle is defined between the first and second rotational axes;
• a second angle is defined between the first and second steering axes;
• and,
• the electromagnetic radiation manipulator is configured to introduce a difference between the first angle and the second angle, wherein the optical scanner comprises a first mirror and a second mirror that are non-rotatable with respect to each other.
