    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: 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 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 generating an image having extended depth of field. The system includes a phase mask and a chromatic wavefront coding lens. The chromatic wavefront coding lens provides axial color separation of light by generating specified chromatic aberration in an image created by the lens. The phase mask causes the optical transfer function of the optical system to remain substantially constant within a specified range away from the image plane, and the optical transfer function of the system contains no zeroes within at least one spectral passband of interest. Digital processing may be performed on the image to generate a final image by reversing a decrease in modulation transfer function generated by the phase mask.

    摘要: A strategic default score is determined for an entity that characterizes a likelihood of the entity voluntarily electing to default on a loan. Data characterizing credit data and valuation data of an asset owned by the entity is received. Using the received data, the strategic default score is generated which characterizes a likelihood of the entity to voluntarily elect to default on the loan when the entity is capable of paying-off the loan. Provision (e.g., display, transmission, storage, etc.) of the strategic default score is then initiated. Related apparatus, systems, techniques and articles are also described.

    摘要: An infrared cut filter may be used with an image sensor to remove infrared light components from image light received from a first side of the infrared cut filter prior to the image light reaching the image sensor to be disposed on a second side of the infrared cut filter. The infrared cut filter includes at least one red absorbing layer and an infrared reflector. The at least one red absorbing layer partially absorbs red light components within the image light. The infrared reflector reflects the infrared light components. The infrared reflector is disposed between the red absorbing layer and the first side of the infrared cut filter while the at least one red absorbing layer is disposed between the infrared reflector and the second side of the infrared cut filter.
