Single-exposure superresolved interferometric microscopy (SESRIM) by RGB multiplexing has recently been proposed as a way to achieve one-dimensional superresolved imaging in digital holographic microscopy by a single-color CCD snapshot [Opt. Lett. 36, 885 (2011)]. Here we provide the mathematical basis for the operating principle of SESRIM, while we also present a different experimental configu...

We have developed and successfully demonstrated a high speed, low noise camera system for crystallography and X-ray imaging applications. By coupling an EM-CCD to a 3:1 fibre optic taper and a CsI(Tl) scintillator it was possible to detect hard X-rays. This novel approach to hard X-ray imaging takes advantage of the low equivalent readout noise performance at high pixel readout frequencies of E...

Biophotonic imaging with ultrasound-modulated optical tomography (UOT) promises ultrasonically resolved imaging in biological tissues. A key challenge in this imaging technique is a low signal-to-noise ratio (SNR). We show significant UOT signal enhancement by using intense time-gated acoustic bursts. A CCD camera captured the speckle pattern from a laser-illuminated tissue phantom. Differences...

Creating virtual environment models often requires geometric data from range sensors as well as photometric data from CCD cameras. The model must be geometrically correct, visually realistic, and small enough in size to allow real-time rendering. We present an approach based on 3D range sensor data, multiple CCD cameras, and a colour high-resolution digital still camera. The multiple CCD camera...

Objective: It is important to observe eye movements in order to evaluate peripheral or central vestibular disorders in dizzy patients. An infrared rays charge coupling device (IR-CCD) camera is now widely used in daily practice. The technical advantage of a complementary metal oxide semiconductor (CMOS) now allows us to develop an inexpensive handmade camera for carrying out nystagmus recording...

This paper describes a CCD (charge coupled device) camera-based hyperspectral imaging system designed for both stationary and airborne remote sensing applications. The system consists of a high performance digital CCD camera, an imaging spectrograph, an optional focal plane scanner, and a PC computer equipped with a frame grabbing board and camera utility software. The CCD camera provides 1280(...

A novel measuring system based on a single non-metric CCD camera and a laser projector is proposed in this paper for measuring distance of a remote object. The setup of the measuring system is relatively easy, in which the laser pointer is positioned beside the CCD camera so that laser beam projected is parallel to the optical axis of the camera in a fixed distance. Based on a fast and effectiv...

In this paper we developed and manufactured a low-cost pc-based hand geometry verification system that can be used in various access control applications. The s/w and h/w were optimized for the code, speed, performance, and for cost. A new algorithm for the extraction of the hand geometry characteristic features based on anatomical landmarks (fingertips and bottom of valleys between fingers) we...

This work purposes using a 3D PMD camera as a sensor for mobile robot applications. The use of image sensors for environment detection is substantial and common usage in mobile robot exploration. Laser scanners, 3D stereo vision or a combination of them are be used generally. The PMD camera is a novel 3D measuring system, which is based on a time-of-flight principle. The main feature is an arra...
