An image generating system that generates a focal image of a target object on a virtual focal plane located between a plurality of illuminators and an image sensor (b) carries out the following (c) through (f) for each of a plurality of pixels constituting the focal image, (c) carries out the following (d) through (f) for each of the positions of the plurality of illuminators, (d) calculates a position of a target point that is a point of intersection of a straight line connecting a position of the pixel on the focal plane and a position of the illuminator and a light receiving surface of the image sensor, (e) calculates a luminance value of the target point in the captured image by the illuminator on the basis of the position of the target point, (f) applies the luminance value of the target point to the luminance value of the pixel, and (g) generates the focal image of the target object on the focal plane by using a result of applying the luminance value at each of the plurality of pixels.

An infrared imaging system includes a phase grating overlying a two-dimensional array of thermally sensitive pixels. The phase grating comprises a two-dimensional array of identical subgratings that define a system of Cartesian coordinates. The subgrating and pixel arrays are sized and oriented such that the pixels are evenly distributed with respect to the row and column intersections of the subgratings. The location of each pixel thus maps to a unique location beneath a virtual archetypical subgrating.

There is provided an imaging device capable of improving the image quality of a reconstructed image in lensless imaging, and a method for operating the imaging device. In lensless imaging, a selection filter is provided that, for each of a plurality of regions into which an imaging surface on the imaging element is divided, allows only the modulated light having optical characteristics that are orthogonal to each other between the regions adjacent to each other, to pass through. With a sub-area set for each selection filter as a unit, the modulation mask converts the incident light into modulated light having optical characteristics corresponding to the selection filter based on at least one of polarization and spectroscopy. The present disclosure can be applied to an imaging device.

A method for performing high dynamic range optical image detection of a scene. The method comprises imaging incident light from a scene onto an object plane of an Optical Array Device, the OAD operating in time modulation mode; determining the locations of those pixels in the object plane of a first light level; detecting the optical irradiance values of those pixels of the first light level to produce a first detected image; detecting the optical irradiance values of those pixels of a second light level to produce a second detected image; and generating a high dynamic range optical irradiance map of the scene by combining the first detected image and the second detected image into a single image.

The present technology relates to an optical element and an optical device that enable resolution of a light image to be increased at a position according to the position of the light image to be detected in an optical element that forms an image without a lens.

The optical element includes an optical element plate that includes, in part, a light transmission part forming a light image of an object by light from the object, the light having passed through a transparent zone that transmits light, and that blocks light in a portion other than the transparent zone, in which the transparent zone is formed such that resolution of a light image formed in a direction different from a normal direction of a plate surface of the optical element plate with respect to the light transmission part is higher than resolution of a light image formed in the normal direction.

A radiation camera system and method incorporating a radiation sensor/detector (RSD) and automated operation of coded camera aperture masks (CAMs) is disclosed that may be advantageously applied to real-time tracking of radiological hot spots in crisis, maintenance, decontamination, and/or maintenance scenarios. The system/method integrates automated camera RSD positioning, CAM identification, and CAM rotation. The system incorporates computerized controls in conjunction with remotely controlled horizontal/vertical tilting motors to direct the RSD aperture position and view of the RSD. CAMs may be installed in the camera manually and are automatically identified by the system via the use of encoding magnets that are detected using a Hall-effect sensor. The CAMs may be rotated after installation in the camera by computer control to predefined positions such as mask and anti-mask to affect the desired degree of radiation screening to be applied to the RSD.

A machine vision system and method use lensless near-contact imaging with coherent illumination, or incoherent illumination, and high pixel count large format sensors (e.g., equivalent to at least 20 to 65 mega-pixels) to produce diffraction patterns of the micro-objects or the gray scale images of the micro-objects over a large overall field-of-view of the machine vision system. The machine vision system provides feedback to a microassembler system to position, orient, and assemble microscale devices like micro-LEDs over large working areas. The effective resolution of the machine vision system can be further improved through the use of gray scale and super-resolution image processing techniques.
