      Although distortion can often be troublesome in measurement applications, it is important to note that no information about the object is actually lost, but merely misplaced in the image. Using these targets, one can easily determine the precise amount of distortion present and back it out of measurements. The dot center can be located using blob (or centroid) analysis in measurement software. To accommodate the expanding variety of image analysis software and applications we offer fixed frequency and variable frequency targets. The fixed frequency targets are available in 3 standard options each with a different dot size/dot frequency combination. Choose a target based on your field of view or resolution/accuracy requirements. These targets are available in either a chrome on glass or a white reflective MylarR/photo emulsion target to accommodate transmission or reflection based applications respectively. Included in the packaging is a serialized N.I.S.T. Traceable Certificate of Accuracy per MIL-STD-45662A. Click here to reference MIL SPEC MIL-STD-45662A (PDF 419kb)

    ■DOF 5-15 Depth of Field Target DOF 5-15 景深校驗片 ■
    ccd解析校驗片
    • Test Depth of Field of Your Imaging System
    • Effective Measurement Eliminates the Need for Calculations
    • 測試影像系統的景深
    • 有效的量測可免去演算
    This unique target was developed to standardize an area of optical to lerancing that is most commonly determined theoretically. Our extensive experience in designing optical systems has shown that depth of field calculations can often yield very misleading results. This target solves the problem and very accurately determines the amount of shift an object can undertake before producing an unacceptable image. The definition of what constitutes an acceptable image is determined by the user and the application. The DOF 5-15 is made up of two sets of scales. Each, when viewed at 45°, consists of horizontal and vertical lines at a frequency of 5 and 15 line pairs per mm. Instructions included.
    過去光學設計顯示,往往產生計算景深誤導結果,
    此校驗片可克服相關問題並於產生不明確影像前精確定義,定義影像構成圖,是依使用者及應用來決定,DOF-15有兩種量測刻度,每一種當以45度角觀看時,會在頻率每毫米5和15條組成平行及垂直線路,此校驗片包含使用說明。

    ■ 1951 USAF Contrast Resolution Target 1951 USAF 對比解析校驗片 ■
    ccd解析校驗片
    • 15 USAF Targets Which Vary in Density
    • Allows Resolution Measurements at Different Contrast Levels
    • 15種USAF校驗片可改變各種密度
    • 可於不同對比程度解析量測

    Since imaging systems are often classified in terms of resolution and contrast, our photographic paper targets allow users to evaluate their systems using the standard USAF format for resolution measurements at different contrast levels. For example, they are useful when lens designers develop lens systems to provide high contrast at low resolution, but neglect contrast at higher resolutions. They prove handy when two lens designs have the same limiting resolution, but drastically different contrast performance at lower resolutions. By imaging targets of various contrast, the user can make qualitative comparisons between lenses as well as evaluate the performance of the system for objects with varying or low contrast levels.
    自從影像系統常依解析度跟對比被分類,相片紙校驗片可讓使用者評估他們的系統在不同的對比等級使用標準的對比解析校驗片測量,舉例說明,當鏡片設計師發展系統鏡片來提供高對比低解析度,但忽略了高解析上的對比,他們簡單的證實了當兩個鏡片設計有一樣限制性的對比及低解析度,但對比成效卻大大的不同, 藉由影像的各種對比,使用者可於兩種鏡頭中做定性比較及評估該性能不同的低對比度。

    Since imaging systems are often classified in terms of resolution and contrast, our photographic paper targets allow users to evaluate their systems using the standard USAF format for resolution measurements at different contrast levels. For example, they are useful when lens designers develop lens systems to provide high contrast at low resolution, but neglect contrast at higher resolutions.

By imaging targets of various contrast, the user can make qualitative comparisons between lenses as well as evaluate the performance of the system for objects with varying or low contrast levels.
    成像系統通常分為分辨率和對比度, 因此此校驗片可於不同對比程度中量測出其USAF解析值,例如,當設計出的鏡頭系統在低解析下提供高對比影像, 卻忽略高解析下的對比, 藉由影像的各種對比,使用者可於兩種鏡頭中做定性比較及評估該性能不同的低對比度。

    ccd解析校驗片
    • 15 Density Steps
    • Logarithmic Grayscale
    • 15種密度
    • 對數灰階

    This 8.5" x 11" white photographic paper variable density target offers a convenient means of testing the gray level performance of optical systems. There are 15 density steps from a density of 0.09 to 1.5 on two progressions from high to low and low to high.This corresponds to optical density increments of 0.10. The variation between density steps is linear, which leads to a logarithmic change in diffuse reflectivity. Since a logarithmic reflectivity progression offers both finer and coarser incrementation than a comparable linear chart, it is often preferable for system testing. Paper is 0.2mm thick. White matte photographic paper.
