The invention relates to a transmission electron microscope equipped with a 2k−2k pixel area Slow Scan Cooled Charge Coupled Device Camera connected to an image processing software for generating an image of a sample. A segmentation of gold particles in the sample is achieved by the separation from specimen structure and background noise. An identification and classification of particle types is carried out according to the shape and size of the detected particles or particle pairs and finally, the gold particle distribution is visualized by the generation of false color overlay images as well as the indication of the numbers in the image.

A charge coupled device camera (7) is incorporated into one wing (2) of a portable personal computer (1). A document (16), such as a business card, is placed on the other wing (3), secured by means of clips (15a,15b,15c,15d) or transparent ribbons (125a,125b,125c,125d) and photographed. Blurring of the captured image is reduced because the camera and the document are mounted to the same substrate. Also, optimal positioning of the document is achieved more quickly and easily using this arrangement than using a separate stand to mount the document.

In a luminescence detecting apparatus and method for analyzing luminescent samples, luminescent samples are placed in a plurality of sample wells in a tray, and the tray is placed in a visible-light impervious chamber containing a charge coupled device camera. In the chamber, light from the luminescent samples pass through a collimator, a Fresnel field lens, an infrared filter, and a camera lens, whereupon a focused image is created by the optics on the camera. The use of an infrared filter suppresses stray IR radiation resulting from plate phosphorescence (which can result in abnormally high backgrounds and/or alteration of the image received by the camera).

The microscope (S, 100) of the present invention has a hand piece (20, 112), whose tip is mounted with a thin sheet-like mirror unit (M, 10, 130, 220), and around both ends of the base (11c, 131c) thereof is arranged an illuminating light source (32, 117), whereby light is emitted to a target object, image light is lead through the light reception bore (27, 116), to the optical system (114), and is recorded at the CCD camera (111), to obtain video images. The thin sheet-like mirror (M, 11, 131) confines light and navigate it, wherein the width of the mirror can be made narrower like a convergent taper surface (11a, 131a); and it is comprised of a base surface (11c, 131c) where illuminating light comes in and image light goes out, and a mirror surface (11b, 131b) where illuminating light and image light go back and forth, and make the reflection thereof, and the mirror surface (11b, 131b) is slanted to 45 degrees. The microscope may be used as a handy microscope if it is not equipped with a charge-coupled device camera. The microscope can provide a wider horizon, which makes it possible to make a horizontal observation in an extremely narrow space, and can be manufactured at a less expensive price.

A CCD-based biochip reader includes a light source for emitting light beams, a collimating lens for converting the light beams into wide parallel rays of light, passing said wide parallel rays of light through a biochip and exciting fluorescence from fluorescent targets on the biochip, a focusing lens for focusing the fluorescence, a filter for filtering out said parallel rays of light, and a charge-coupled device camera for generating images from said fluorescence. For recording intensity of the fluorescence from the fluorescent targets, images of the charge-coupled device camera is converted into digital data through an image converting device. Wide parallel laser beams are produced by the laser and through the collimating lens, and excite all samples on the biochip with high efficiency at the same time. In addition, time for analysis is saved when fluorescent images of a large area on biochips are collected and analyzed through the charge-coupled device camera.

A wafer is positioned on a wafer support apparatus beneath an electrode such that a plasma generation region exists between the wafer and the electrode. Radiofrequency power is supplied to the electrode to generate a plasma within the plasma generation region. Optical emissions are collected from the plasma using one or more optical emission collection devices, such as optical fibers, charge coupled device cameras, photodiodes, or the like. The collected optical emissions are analyzed to determine whether or not an optical signature of a plasma instability exists in the collected optical emissions. Upon determining that the optical signature of the plasma instability does exist in the collected optical emissions, at least one plasma generation parameter is adjusted to mitigate formation of the plasma instability.

A micro-image examining apparatus includes a conveyor belt for moving at least one object to be examined and a microphotographer including a charge-coupled device camera and a lens for acquiring an image of the object on the conveyor belt and for sending the image of the object to a computer monitor. Thus, the objects to be examined are placed on the conveyor belt and moved synchronously. Instead of conventional one-by-one examination by workers, the objects are examined one by one by the microphotographer. The examining efficiency and the examining accuracy are both improved.

In a control method of a CCD (Charge-Coupled Device) camera, control traces for a zoom lens and a focus lens of the camera are adjusted in accordance with pre-stored trace data so as to compensate a focus error in accordance with the use or not of an OLPF (Optical Low Pass Filter) in automatic adjustment of the focus lens and the zoom lens. Accordingly, because a photographing mode can be converted into a daytime mode or a nighttime mode without changing a lens unit, the facility of user can increase, the price can be reduced and miniaturization of a CCD camera can be performed by eliminating a dummy glass for adjusting a refractive index when not using the OLPF.

A Real-Time Optical Correlating System produces holograms that contain both amplitude and phase information and have none of the time constraints of the traditional holographic methods. It has been demonstrated to operate at television field rates (60 Hz) employing currently available devices of moderate resolution. Using the System, the holographic matched filter of an input scene is calculated optically as an analog sum, captured by a charge-coupled device (CCD) camera and transmitted directly or through a computer to and displayed on a commercially available liquid crystal display (LCD) device. The correlation plane may be viewed immediately on a suitable screen because there is no film to process or computer calculations to be performed. Concurrently with the creation of the holographic matched filter of the input scene, a Fourier transform of a test scene is produced and both are imaged on another charge-coupled device camera for any correlation between the input and test scenes.
