Abstract: Wavefront sensors are provided herein. An aperture mask is configured to receive incident light the wavefront of which is to be measured and comprising irregularly spaced apertures that respectively transmit sub-beams of the incident light. A diffuser is configured to receive the sub-beams transmitted by irregularly spaced apertures of the aperture mask. A camera, having a focal plane in which the diffuser substantially is located, is configured to obtain a digital image of the diffuser and thus to obtain a digital image of the incident light the sub-beams of which the aperture mask transmits onto the diffuser. A controller is configured to electronically receive the digital image of the diffuser and to measure the wavefront of the incident light based on the digital image. Methods also are provided.

Abstract: Methods of generating a camera model are provided. A robotic assembly is used to move a calibration assembly relative to a camera assembly through a series of poses. The calibration assembly comprises a calibration target and markers. The camera assembly comprises a mount, a camera having a field of view, and markers. The predetermined series of poses, together, cause the calibration target to pass through the field of view of the camera. The camera is used to generate a respective image of the calibration target. A tracker is used, to determine respective locations in space of the markers. A transformation function is generated that maps onto a three-dimensional space the stored coordinates and determined locations in space of the markers and features of the calibration target. The transformation functions are used to generate a model of parameters of the camera. Systems are also provided.

Abstract: A light module is removably coupleable to a light fixture and includes an LED lighting element mounted on a mounting base that is operatively coupled to a housing. The light module also includes one or more resilient members that operatively couple the mounting base to the housing and allow the mounting base and housing to resiliently move relative to each other. The resilient members compress when the light module is removably coupled to the light fixture to exert a generally axial force on the mounting base to drive the mounting base into resilient contact with a surface of the light fixture to provide a thermal coupling between the light module and the light fixture.

Abstract: A lighting assembly and a method for manufacturing a lighting assembly are provided. The lighting assembly includes a light module including a lighting element, and an enclosure having a recess for receiving and housing the light module. The lighting assembly also includes a thermally conductive core connected to the light module through the enclosure. The lighting assembly further includes a housing mounted in thermal contact with the core and the enclosure, so as to cause the housing to dissipate heat to an ambient atmosphere.
