Electronic spot light control

An optical system, comprising:

• spot size control optics receiving a beam of light, adjusting a lateral extent of the beam of light and outputting the beam of light;
• and
• focus control optics coupled to an actuator responsive to electrical signals, the focus control optics receiving the beam of light, altering a position of a focus of the beam of light and outputting the beam of light, the beam of light having a first focus position for a first lateral component of the beam of light and having a second focus position for a second lateral component of the beam of light, the first lateral component perpendicular to the second lateral component, the focus control optics adjusting the first focus position to a greater extent than the second focus position in response to the electrical signals supplied to the actuator.

An optical system, comprising:

• spot size control optics receiving a beam of light, adjusting a lateral extent of the beam of light and outputting the beam of light, the beam of light having a first extent in a first lateral direction and a second extent in a second lateral direction perpendicular to the first lateral direction, the spot size control optics coupled to a spot size actuator and responsive to electrical signals to adjust an ellipticity of the beam, wherein movement of the spot size actuator alters the first lateral extent of the beam of light more than the second lateral extent;
• and
• focus control optics coupled to a focus actuator responsive to electrical signals, the focus control optics receiving the beam of light, altering a position of a focus of the beam of light and outputting the beam of light, the beam of light having a first focus position for a first lateral component of the beam of light and having a second focus position for second lateral component of the beam of light, the first lateral component perpendicular to the second lateral component, the focus control optics adjusting the first focus position to a greater extent than the second focus position in response to the electrical signals supplied to the focus actuator.
