Large diopter range real time sequential wavefront sensor
Example embodiments of a large dynamic range sequential wavefront sensor for vision correction or assessment procedures are disclosed. An example embodiment optically relays a wavefront from an eye pupil or corneal plane to a wavefront sampling plane in such a manner that somewhere in the relaying process, the wavefront beam from the eye within a large eye diopter range is made to reside within a desired physical dimension over a certain axial distance range in a wavefront image space and/or a fourier transform space.

Optical guide for collimated images with optical beam doubler, and associated optical device
The general field of the invention is that of optical guides for collimated images comprising a first and a second image conductor functioning by total reflection, each conductor comprising a plurality of plates that are planar, semi-reflective, mutually parallel and inclined with respect to the plane of the external faces of the image conductors. The two conductors are arranged so as to deliver a collimated image to a large pupil.

Optical apparatus
An optical apparatus includes: laser; objective that irradiates a sample with laser light; phase-modulation spatial light modulator that is located at a pupil conjugate position of the objective and modulates a phase of the laser light; scan unit that scans the sample with the laser light; detector that detects observation light from the sample; image generating unit that generates a sample image according to a signal from the detector and control information of the scan unit; and controlling unit that sets for the modulator a modulation amount of the phase of laser light in accordance with a pattern to be formed on the sample using the laser light. According to the pattern to be formed on the sample and a pattern of irradiation with the laser light obtained from the image generated by the image generating unit, the controlling unit corrects the modulation amount that is set for the modulator..

Application of electromagnetic radiation to the human iris
Rather than rely solely upon pupillary occlusion or tracking of eye movement to protect the fundus from accidental exposure to electromagnetic radiation, the present invention also utilizes an electromagnetic radiation pathway with a profile such that the energy density at the iris is greater than the energy density at the posterior portion of the eye. This disparity in energy density allows for efficacy at the anterior iris treatment site, without injury to the fundus..
