General purpose, high accuracy dosimeter reader

A general purpose high accuracy dosimeter reader, 80, for determination of a treatment condition, based on comparison of an image of treated dosimeter, 111, with a series of images of pre-treated dosimeter, 114, is disclosed. A dosimeter undergoes noticeable changes, such as a color change upon treatment with certain materials, such as toxic gases and processes, such as ionizing radiation and sterilization is pre-treated. The dosimeter is imaged with an imaging device, 115, such as charge-coupled device camera and images of the dosimeter or the changes, e.g., color change, are stored in an information storage device, 118. In order to determine the treatment condition, the treatment dosimeter is imaged and the image is compared with the series of pre-treated images of the dosimeter using software. The closest match of the treated dosimeter with the pre-treated and pre-imaged dosimeter would indicate the treatment conditions. The process and device can be used for almost any indicating device, process and treatment.

Systems and Methods for Detection of Plasma Instability by Optical Diagnosis

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.

Real-time optical correlating system

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.
