    摘要： A method for designing a first optical filter, exhibiting a first filter performance satisfying a first preset criterion, and a second optical filter, exhibiting a second filter performance satisfying a second preset criterion, includes providing initial first and second filter designs for the first and second optical filters, respectively, as first and second ordered stacks of layers, respectively. A pair of layers, including a first layer, characterized by a first thickness, and a second layer, characterized by a second thickness, is selected from the first and second ordered stacks of layers. The first thickness is constrained to a first constrained thickness that is a positive integer multiple of the second thickness to yield a constrained first filter design. A predicted performance of the constrained first filter design is determined and compared with the first preset criterion for one of accepting and rejecting the constrained first filter design.

    摘要： A multilayer optical device includes an arrangement, on a substrate, of a first layer, a second layer, and a space therebetween. The second layer is a thin-film. The arrangement of the first and second layers and the space therebetween produces transmitted, reflected, or dispersed spectrally modified electromagnetic energy from electromagnetic energy incident upon the arrangement. An optical function of the device is dependent at least in part on interference effects. An optical detector system includes a similar multilayer optical device. The space within the device is in fluid communication with structures for receiving a fluid such that the device operates in a first or second mode depending on absence or presence of the fluid within the space. The system includes a detector for receiving the modified electromagnetic energy, and a controller in fluid communication with the space that establishes the absence or presence of the fluid in the space.

    摘要： An optical system for capturing three-dimensional images of a three-dimensional object is provided. The optical system includes a projector for structured illumination of the object. The projector includes a light source, a grid mask positioned between the light source and the object for structured illumination of the object, and a first Wavefront Coding (WFC) element having a phase modulating mask positioned between the grid mask and the object to receive patterned light from the light source through the grid mask. The first WFC element is constructed and arranged such that a point spread function of the projector is substantially invariant over a wider range of depth of field of the grid mask than a point spread function of the projector without the first WFC element.

    摘要： A task-based imaging system for obtaining data regarding a scene for use in a task includes an image data capturing arrangement for (a) imaging a wavefront of electromagnetic energy from the scene to an intermediate image over a range of spatial frequencies, (b) modifying phase of the wavefront, (c) detecting the intermediate image, and (d) generating image data over the range of spatial frequencies. The task-based imaging system also includes an image data processing arrangement for processing the image data and performing the task. The image data capturing and image data processing arrangements cooperate so that signal-to-noise ratio (SNR) of the task-based imaging system is greater than SNR of the task-based imaging system without phase modification of the wavefront over the range of spatial frequencies.

    摘要： A method for generating an output image of a scene is disclosed. A detector of a task-based imaging system includes a plurality of pixels, and the scene includes at least one object located at a given object distance within a range of object distances between the object and the imaging system. The method includes capturing a high resolution image of the scene, converting the high resolution image into an image spectrum of the scene, determining a defocused optical transfer function (OTF) of the imaging system over the range of object distances and determining a pixel modulation transfer function (MTF) over the plurality of pixels. The method also includes multiplying the image spectrum with the OTF and the MTF to generate a modified image spectrum of the scene, converting the modified image spectrum into a modified image of the scene, and generating the output image from the modified image.
