Abstract
A method and apparatus for fixation measurement includes rotating a first reflector comprising a diffraction component about a rotation axis, the first reflector being configured to reflect light received from a light source onto a second reflector via the diffraction component and reflect light received from the second reflector via the diffraction component and capturing light which is reflected by the second reflector and subsequently reflected by the first reflector with one or more photodetectors.
Claims20
An apparatus for fixation measurement, the apparatus comprising:
- a first reflector comprising a diffraction component, wherein the first reflector is configured to rotate about a rotation axis, reflect light received from a light source onto a second reflector via the diffraction component, and reflect light received from the second reflector via the diffraction component;
- and
- one or more photodetectors configured to capture light which is reflected by the second reflector and subsequently reflected by the first reflector;
- wherein a combination of a reflective component in the first reflector and the diffractive component in the first reflector is configured to rotate and re-image a waist of the light received from the light source onto the second reflector without inducing torque.
