Abstract: Disclosed herein is a display device including at least one illumination source configured for projecting at least one illumination beam on at least one scene; at least one optical sensor having at least one light sensitive area, where the optical sensor is configured for measuring at least one reflection light beam generated by the scene in response to illumination by the illumination beam; at least one translucent display configured for displaying information, where the illumination source and the optical sensor are placed in direction of propagation of the illumination light beam in front of the display, and at least one control unit, where the control unit is configured for turning off the display in an area of the illumination source during illumination and/or in an area of the optical sensor during measuring.

Abstract: Methods and systems are disclosed for improvements in aquaculture that allow for increasing the number and growth efficiency of fish in an aquaculture setting (or other animals in other settings) by identifying or predicting characteristics of the animals based on visual or ultrasound images of the animals obtained through non-invasive means. The animals are sorted based on the characteristics.
