Hologram Scaling, Physics 3901, Fall 02
Experimenters: Kyle Setchel, Zhuo (Jimmy) Tan, Theresa Crider-Cox, Steve Gerber
![]() | A view of the holographic image formed by a clear mercury vapor lamp was made with a digital video camera. This image is a single frame from the digital video. The diameter of the pipe in the image can be resolved for the green and orange lines, but not for the blue. For the green and blue images, a measurement of well defined features could be made as indicated by the lines on the image. In this way, relative sizes for the three wavelengths could be obtained.
用清晰的汞灯形成的全息图像通过数字视频相机拍摄。这张图像是一帧数字视频。图像中管道的直径可以分辨出绿色和橙色线,但不能分辨蓝色线。对于绿色和蓝色图像,可以测量到明确的特征,如图像上的线条所示。这样就可以获得三种波长的相对尺寸。 |
![]() | Relative measurements were made of the image size for the three wavelengths of the mercury spectrum, 436, 546, and 578 nm. The measurements were made using the ruler capability in Adobe Photoshop. The relative image sizes for the three wavelengths were plotted with Kaleidograph. 为了测量汞谱线三个波长(436、546 和 578 纳米)的像大小,使用 Adobe Photoshop 的尺子功能进行了相对测量。这三个波长的相对像大小通过 Kaleidograph 进行了绘制。

![]() | This view looks sharper, and better measurements were anticipated. But the scaling factor was quite a bit less. To compare green and orange, the width of the pipe was used. For the blue and green relative scaling, the height of the pipe to the point of attachment of the supporting rod was used.
这种视图更清晰,预期能进行更精确的测量。但缩放因子却相当小。为了比较绿色和橙色,使用了管道的宽度。对于蓝色和绿色的相对缩放,使用了管道到支撑杆连接点的高度。 |
