Thereby, it is possible to suppress the amount of light when an optical image which is focused at the front of an optical image made incident into the first imaging device (front focus) and an optical image which is focused at the rear thereof (rear focus) are respectively imaged at the second imaging device and also to secure the amount of light on image pickup by the first imaging device. Further, in the image capturing apparatus, a position of the first imaging region and a position of the second imaging region on the imaging area are reversed with respect to the axis P in association with reversal of a scanning direction of the sample. Therefore, despite the scanning direction of the sample, it is possible to obtain a deviation direction of the focus position under the same conditions.

    Abstract: A new digital image/video camera that directly acquires random projections of the incident light field without first collecting the pixels/voxels. In one preferred embodiment, the camera employs a digital micromirror array to perform optical calculations of linear projections of an image onto pseudorandom binary patterns. Its hallmarks include the ability to obtain an image with only a single detection element while measuring the image/video fewer times than the number of pixels or voxels—this can significantly reduce the computation required for image/video acquisition/encoding. Since the system features a single photon detector, it can also be adapted to image at wavelengths that are currently impossible with conventional CCD and CMOS imagers.

  • Patent number: 8786767
    Abstract: This document describes various apparatuses and techniques for rapid synchronized lighting and shuttering. These apparatuses and techniques are capable of capturing two images, where one of the images integrates multiple exposures during which an image area is illuminated by a light source and another of the images integrates multiple exposures during which the image is not illuminated by the light source. The image area can be illuminated by rapidly flashing the image area with the light source and synchronizing a shutter to permit one image sensor to capture an image when the image area is illuminated and another image sensor to capture the image area when the image area is not illuminated. These two images can be captured concurrently or nearly concurrently, thereby reducing or eliminating motion artifacts. Further, these apparatuses and techniques may do so with slow and relatively low-cost cameras and relatively low computational costs.

  • Patent number: 8717466
    Abstract: An imaging system and method that captures compressive sensing (CS) measurements of a received light stream, and also obtains samples of background light level (BGLL). The BGLL samples may be used to compensate the CS measurements for variations in the BGLL. The system includes: a light modulator to spatially modulate the received light stream with spatial patterns, and a lens to concentrate the modulated light stream onto a light detector. The samples of BGLL may be obtained in various ways: (a) injecting calibration patterns among the spatial patterns; (b) measuring complementary light reflected by digital micromirrors onto a secondary output path; (c) separating and measuring a portion of light from the optical input path; (d) low-pass filtering the CS measurements; and (e) employing a light power meter with its own separate input path. Also, the CS measurements may be high-pass filtered to attenuate background light variation.

    Abstract: An imaging system or camera having an array of elements switchable between two states for measuring of light received by the imaging system on a pixel by pixel basis to form two separate images simultaneously over a common integration time in which switching takes place faster than the integration time of the camera. Optical switching may be provided by a spatial light modulator along one of two paths each associated with a detector for one of the images, or each path being associated with one of two non-overlapping regions of the same detector, where each region provides one of the images. Electronic switching may be provided in which for each pixel a photodetector provide an electrical signal onto a switching element which switches the signal onto one of two sites for integrating the signal and providing a pixel value, where the two sites are each associated with a different one of the images.

  • Patent number: 8681184
    Abstract: A display unit for binocular representation of a multicolor image including a control unit triggering an imaging element such that the imaging element generates in a temporal successive manner the image to be displayed for a first beam path and a second beam path as a first image and second image, respectively. The images are generated in a pre-distorted manner, opposite of the chromatic aberration of the respective beam path, such that the chromatic aberration generated in the respective beam path is compensated when the first and second image is displayed. The display unit includes a switching module which operates in temporal synchrony with the first and second image being generated, such that a user can see the first image only via the first beam path and the second image only via the second beam path.

  • Publication number: 20140071329
    Abstract: An optical device having a total internal reflection (TIR) switch is able to switch to form two different optical imaging paths. Each optical imaging path has different optical characteristics that causes a detector to capture different imagery depending upon which optical imaging path is used. The TIR switch is switchable between a TIR state and a transmission state to control which optical imaging path is used by the device for imaging.

  • Patent number: 8638387
    Abstract: A sighting system is disclosed, comprising a housing with small upper mirror mounted in its upper center, redirecting light from a single objective lens set, and a larger lower mirror mounted coaxially relative to the lens set and upper mirror, both mirrors set at 45° and redirecting light at 90° angles to the lens set. The smaller mirror is positioned closer than the lower mirror to the lens set. A night camera system is used for receiving an image through the lens set redirected by the lower mirror and amplified through an intensifier before transmission to a video display monitor(s). A day camera system receiving the image from the lens set redirected by the smaller mirror transmits the image to the monitor(s) for separate display of the image, enabling simultaneous capture of the optimum amount of light by each camera, maximizing the housing's diametrical space to receive incoming light.
