摘要： Light-sensor array systems for capturing multiple-color images and light-fields using array of wavelength-selective optoelectronic elements (rather than wider-range photosensors prefaced with visible-band wavelength-selective optical elements such as color selective filters) as light-field or image sensors are presented. The light-sensor array can be one or more of transparent, bendable, and implemented on a curved surface. In some embodiments, the wavelength-selective light-sensing opto-electronic elements are arranged in a stacked array. In some embodiments, more than three wavelength-selective ranges can be employed in each light-sensing pixel. The invention can be used to implement one or more of a lensless imaging light-field camera, tactile gesture user interface, and/or proximate gesture user interface. In some embodiments, the light-sensor array system can be configured to emit light of one or more colors, and thus can additionally serve as an image display. In some embodiments, the wavelength-selective light-sensing opto-electronic elements are co-optimized for light sensing and emission.
