52 ProEM System Manual Issue 3
Briefly:
• In Focus {Preview} mode, the number of frames is ignored. A single frame is
acquired and displayed, another frame is acquired and overwrites the currently
displayed data, and so on until Stop is selected. In WinX, the last frame acquired
before Stop is selected can be stored; in LightField, this frame cannot be stored.
Focus {Preview} mode is particularly convenient for familiarization and setting
up. For ease in focusing, the screen refresh rate should be as rapid as possible,
achieved by operating with axes and cross-sections off, and with Zoom 1:1
selected.
• In Acquire mode, every frame of data collected can be automatically stored (the
completed dataset may include multiple frames with one or more
accumulations). This mode would ordinarily be selected during actual data
collection. One limitation of Acquire mode operation is that if data acquisition
continues at too fast a rate for it to be stored, data overflow may occur. In WinX,
this could only happen in Fast Mode operation.
The remainder of this chapter provides First Light procedures (these provide
step-by-step instruction on how to initially verify system operation) and discusses
factors that affect exposure, readout, and digitization of the incoming signal. By
understanding the exposure, readout, and digitization factors and making adjustments
to software settings you can maximize signal-to-noise ratio. Refer to
Chapter 6,
Advanced Topics , on page 89 for information about synchronizing data acquisition with
external devices.
5.1 WinX First Light Instructions
5.1.1 Imaging Applications
This section provides step-by-step instructions for acquiring an imaging measurement
in WinView/32 or WinSpec/32 for the first time. The intent of this procedure is to help
you gain basic familiarity with the operation of your system and to show that it is
functioning properly. Once basic familiarity has been established, then operation with
other operating configurations, ones with more complex timing modes, can be
performed.
Assumptions
The following procedure assumes that
• You have already set up your system in accordance with the instructions in the
previous chapters.
• You have read the previous sections of this chapter.
• You are familiar with the application software.
• The system is being operated in imaging mode.
• The target is a sharp image, text, or a drawing that can be used to verify that the
camera is "seeing" and can be used to maximize focus.
Getting Started
1. Mount a test target in front of the camera.
2. Power ON the camera (the power switch is on the back of the power supply).
NOTE:
The camera must be turned on before WinX is opened, and
WinX must be closed before the camera is turned off.
3. Turn on the computer power.
4. Start the application software.
