    Abstract: A multi-modal imaging device can include a sensor array, a metamaterial filter, and a memory unit. The sensor array can be any suitable sensor which detects incoming light and is capable of recording a received image. The metamaterial filter can be oriented adjacent the sensor array and can be patterned with pixels having varied physical heights designed to diffract an incoming image to produce an engineered response which is sensitive to 2D spatial coordinates (x, y), time (t), and at least one of depth spatial coordinate (z), spectrum (λ), and degree of polarization ({right arrow over (S)}). The memory unit can include instructions that, when executed by a processor, reconstruct the engineered response to produce a reconstructed image which includes the 2D spatial coordinates and at least one of z, λ, and {right arrow over (S)}.

    Abstract: A method for sub-diffraction-limited patterning using a photoswitchable layer is disclosed. A sample of the photoswitchable layer can be selectively exposed to a first wavelength of illumination that includes a super-oscillatory peak. The sample can be selectively exposed to a second wavelength of illumination that does not include the super-oscillatory peak. A region in the sample that corresponds to the super-oscillatory peak and is associated with the second transition state can optionally be converted into a third transition state. The region in the sample at the third transition state can constitute a pattern of an isolated feature with a size that is substantially smaller than a far-field diffraction limit.

    Abstract: A method of programmable photolithography includes positioning (910) a programmable photomask in proximity to a photoresist layer on a sample. The programmable photomask is illuminated (920) with a plurality of different wavelengths of light simultaneously to expose the photoresist layer in a predetermined pattern. The programmable photomask is separated (930) from the photoresist layer and the photoresist layer is developed (940) to create the predetermined pattern in the photoresist layer.

    Abstract: An imaging system can include an optical fiber and a light source for providing optical stimulation to a region of interest along the optical fiber. A camera can capture emission such as fluorescence resulting from the optical stimulation. A cannula configured for implantation into a subject can be configured to direct the emission from the subject. A mating sleeve coupling the cannula to the optical fiber, and configured to support the camera, can include a dichroic mirror to allow the optical stimulation to pass from the optical fiber to the cannula and to redirect the emission from the cannula to the camera.

    Abstract: A multi-spectral imaging (MSI) device can include an imaging plane and a diffractive optic. The imaging plane can include at least two groups of pixels an array of pixels for sensing at least two spectral bands. The at least two spectral bands can include a first spectral band and a second spectral band. The diffractive optic can be configured for diffracting an electromagnetic wave into the at least two spectral bands and focusing each spectral band component of the electromagnetic wave onto the group of pixels for the spectral band to generate an image.
