Abstract: Techniques are described for passive three-dimensional image sensing based on referential image blurring. For example, a filter mask is integrated with a lens assembly to provide one or more normal imaging bandpass (NIB) regions and one or more reference imaging bandpass (RIB) regions, the regions being optically distinguishable and corresponding to different focal lengths and/or different focal paths. As light rays from a scene object pass through the different regions of the filter mask, a sensor can detect first and second images responsive to those light rays focused through the NIB region and the RIB region, respectively (according to their respective focal lengths and/or respective focal paths). An amount of blurring between the images can be measured and correlated to an object distance for the scene object. Some embodiments project additional reference illumination to enhance blurring detection in the form of reference illumination flooding and/or spotted illumination.

Abstract: An apparatus (e.g., a multi-spectral optical filter array, an optical wafer, an optical component) has an aperture mask printed directly thereon, the aperture mask including a positive or negative photoresist. The apparatus includes a substrate having the aperture mask printed on at least one of a light entrance surface or a light exit surface of the substrate so as to provide an aperture over a portion of the substrate. The photoresist from which the aperture mask is formed is photo-definable or non-photo-definable, and is deposited/printed to form the aperture mask on the substrate.

Abstract: A display device is provided that has pixels including a first pixel and a second pixel arranged to be adjacent to each other along a first direction. The pixels include a light emitting region and a color filter. Luminous efficacy of the first pixel is higher than that of the second pixel. In a plane view, a center position of each color filter is shifted in the first direction from a center position of a corresponding light emitting region, and a length parallel to the first direction of the color filter of the first pixel is longer than that of the second pixel. In the first direction, each first pixel is periodically arranged and a pitch of the color filter of each first pixel and a pitch of the light emitting region of each first pixel are different from each other.

Abstract: An optical filter includes a first mirror that has a first uniform thickness, a second mirror that has a second uniform thickness, and a spacer that is positioned between the first mirror and the second mirror. The spacer has a variable thickness along a first axis of the optical filter. In some implementations, a thickness profile of the spacer, along the first axis, includes one or more portions that have a non-linear slope with an absolute value that is greater than zero.
