Abstract: A system for interpreting color includes a camera for capturing images of an environment and a controller in electrical communication with the camera. The controller is programmed to capture an image of the environment using the camera, where the image includes an object, retrieve a color calibration matrix from a non-transitory storage media of the controller, and determine a color of the object in the environment based at least in part on the color calibration matrix and the image of the environment.

Abstract: A holographic display system provides a maximum intensity value of an intermediate image to decrease a graphics speckle noise. The system includes an SLM having a display with a hologram generating unit and a plurality of pixels for modulating a beam of coherent light. The system further includes a beam splitter for splitting the beam into an object beam and an intermediate image beam that is associated with an intermediate image having the noise. The system further includes a camera for capturing the intermediate image, in response to the camera receiving the intermediate image beam. The system further includes a computer having a processor and a CRM. The processor is programmed to generate an actuation signal associated with a corrective holographic phase shift to decrease the noise. The SLM modifies in real-time a holographic phase of the beam per pixel, in response to the SLM receiving the actuation signal.
