摘要： The color response of camera devices may be calibrated, using a correction factor that can account for differences in the spectra of light emitted by different light sources used during calibration. The correction factor may be calculated based on the expected spectral sensitivities of the camera devices, the power spectrum of an actual light source, and the power spectrum of a canonical light source. The correction factor is then applied to adjust a measured color response of a given camera device, so that the adjusted color response is effectively the response of the given camera device if it had been illuminated by the canonical light source. In this manner, any measured color response differences, which may be due to differences between the actual light source used and the canonical light source, can be effectively reduced (if not essentially eliminated.) Other embodiments are also described and claimed.

摘要： To generate data for color pixels in an image, Bayer symmetric interleaved exposures can more evenly spread the long exposure pixels in the vertical direction and produce a higher dynamic range by having pixels with different exposure times interleaved within different rows. Long and short exposure pixels can be interleaved across two adjacent rows to form 4 pixel wide by 2 pixel tall blocks that are repeated across a Bayer pattern color array. In each block, the first row can be three long and one short exposure pixel; and the second row can be three short and one long exposure pixel. The long exposure pixels can form an “L” shaped pattern rotated 90 degrees clockwise; and the short exposure pixels can form an “L” shaped pattern rotated 90 degrees counter-clockwise. Subsequent rows of the blocks may be offset horizontally to form diagonal bands of long and short exposure pixels.
摘要翻译： 为了生成图像中的彩色像素的数据，拜耳对称交错曝光可以在垂直方向上更均匀地展开长曝光像素，并通过在不同的行内具有交错的不同曝光时间的像素产生更高的动态范围。 长和短曝光像素可跨越两个相邻的行进行交织以形成跨越Bayer图案颜色阵列重复的4像素×2像素高的块。 在每个块中，第一行可以是三个长和一个短曝光像素; 并且第二行可以是三个短和一个长曝光像素。 长曝光像素可以形成顺时针旋转90度的“L”形图案; 并且短曝光像素可以形成逆时针旋转90度的“L”形图案。 块的后续行可以被水平偏移以形成长和短曝光像素的对角线。

摘要： A portable, self-contained, electronic radioscopic imaging system uses a pulsed X-ray source, a remote X-ray sensor, and a self-contained, display and controller unit to produce, store, and/or display digital radioscopic images of an object under investigation. An X-ray image sensor configured to spatially sense X-ray radiation pulses includes a pixel clock generator, an integrating CCD camera imager operating in a progressive scan mode providing a discrete pixel readout cycle of sensed X-ray radiation pulses, a sample and hold circuit for sampling the discrete pixel readout responsive to the pixel clock, and an analog to digital converter for digitizing each pixel as the discrete pixel readout is sampled. A digital video transmission system controller board controls the X-ray source for acquiring digitized samples from the X-ray image sensor. The digital video transmission system has a buffer memory for storing digitized pixels received from the analog to digital converter, and is further provided with a serial interface driver for transmitting the digitized pixels. An image processor receives the digitized pixels transmitted by the serial interface driver of the controller for generating a radioscopic image from the digitized pixels.

摘要： Digital pixel data is obtained from radiographic imaging of one or more objects, and corresponds to an imaged area containing a feature to be measured. A data profile for a region around the measured feature is created from the digital pixel data. A reference profile is then created from the data profile. The reference profile represents an expected data profile for a reference condition of the objects, and accounts for the point spread function of the imager. The difference between the data profile and the reference profile is calculated. Based on that difference, the degree by which the actual condition of the objects varies from the reference condition is determined. The calculated difference can be compared to a lookup table mapping previously calculated differences to degrees of variation from the reference condition. The calculated difference can also be used as an input to an experimentally derived formula.

摘要： The present invention provides an excimer laser capable of producing a high quality pulsed laser beam at pulse rates of about 4,000 Hz at pulse energies of about 5 mJ or greater. A preferred embodiment is an ArF excimer laser specifically designed as a light source for integrated circuit lithography. An improved wavemeter with special software monitors output beam parameters and controls a very fast PZT driven tuning mirror and the pulse power charging voltage to maintain wavelength and pulse energy within desired limits. In a preferred embodiment two fan motors drive a single tangential fan which provides sufficient gas flow to clear discharge debris from the discharge region during the approximately 0.25 milliseconds between pulses.
