Abstract: A method for adjusting the apparent brightness of a computer-generated hologram display is disclosed. The method comprises: receiving source data representative of a scene to be displayed as a hologram; determining hologram data to display a computer-generated hologram representing the scene; determining a scene energy based on the source data, the scene energy being quantised using a scale which is non-linear and which has a closer spacing between values in a mid-section of the scale than between values towards a minimum and a maximum of the scale; associating the scene energy with the hologram data; controlling a holographic display according to the hologram data and simultaneously controlling an output power of an illumination source of the holographic display according to the scene energy. A holographic display apparatus implementing the method is also disclosed.

Abstract: A holographic display comprises: an illumination source which is at least partially coherent; a plurality of display elements positioned to receive light from the illumination source and spaced apart from each other, each display element comprising a group of at least two sub-elements; and a modulation system associated with each display element and configured to modulate at least a phase of each of the plurality of sub-elements.

Abstract: The disclosure presents systems and methods for processing a specimen slide using a specimen processing system. Specimen slides may sequentially be ejected from a slide carrier towards a label reader to determine an appropriate processing protocol for the slides. A cracking element may be engaged with the slide carrier prior to ejecting the slide, in order to break or “crack” any residual adhesive bond between edges of a slide and walls of the carrier. The specimen slides may be horizontally aligned and resting on a corresponding plurality of flat shelves, enabling even spacing via gravitational forces. The slides are therefore evenly spaced, enabling damage-free ejection of slides, and proper positioning for additional operations including scanning, viewing, heating, washing, and other processing.

Abstract: Systems and methods that enable automated processing of specimens carried on microscope slides are described herein. In some embodiments, the system can include, for example, a slide ejector assembly having a slide staging device configured to receive a slide and an over-travel inhibitor that includes a first vacuum port positioned to draw a first vacuum between the slide and a standby platform as the slide is moved across at least a portion of the standby platform. The over-travel inhibitor includes a first sensor for detecting a presence of the slide on the standby platform. The system can also include a transfer assembly to transport slides away from the slide ejector assembly. The transfer assembly can include a floating transfer head having a vacuum port for drawing a partial vacuum for holding the slide.
