otf optical transfer function
解釋
光傳送函數-
Fluorescence power transfer function, three - dimensional point spread function ( 3d - psf ) and three - dimensional optical transfer function ( sd - otf ) for the various fluorescent wavelength of the two kinds of fluorescence confocal scanning microscopy are calculated in this paper by using fourier imaging theory. the results show that the fluorescent wavelength has influence on imaging property of confocal microscopy such as spatial cut - off frequency, resolution and 3d - otf. there is a different missing - cone in the 3 - d space of otf when the ratio of excitation wavelength to fluorescent wavelength decreases
本文在sheppard和gumin等人的理論基礎上，利用fourier光學成像理論，討論了不同熒光波長對單光子和雙光子共焦顯微鏡成像特性的影響，導出了單光子和雙光子共焦顯微鏡的熒光功率傳輸函數、三維脈沖響應函數和三維光學傳遞函數，得到了它們在不同激發波長與熒光波長比值時具體的表達式，並且通過數值計算，得到了它們的曲線圖，結果表明：隨著激發波長與熒光波長比值的增加，焦斑的橫向分佈和縱向分佈變窄，橫向解析度和縱向解析度提高，系統的成像效果變好，當激發波長與熒光波長的比值下降到一定程度時，可以看到不同程度的失錐現象。 -
