94 ST-133 Controller Manual Version 3.B When the data is saved, both images are saved in a single *.spe file. The header is followed by frame 1 and then immediately afterwards by frame 2. This system makes it convenient to later load the images from the file for post processing analysis. Notes: 1. For most of the MicroMAX DIF cameras, the ESABI tim[...]

Appendix H DIF Camera 95 EXPOSURE 400 ns READY Figure 51. Freerun Mode Timing Example: Figure 52 shows an experiment where the rising edge of the signal is used to trigger a DG535 Delay Generator, which provides the required delay and triggers a laser source, Q switch, or other device.

Appendix H DIF Camera 99 EEC (External Exposure Control) Gives the user the ability to capture two imag es before readout with a different exposure time for each. EEC uses the external trigger to control the exposure time of the first image and the exposure time set in software to control the exposure time of the second image. When the external tri[...]

100 ST-133 Controller Manual Version 3.B ESABI (Electronic Shutter Active Between Images) The last timing mode, ESABI, allows separation time between the two im ages. This mode gives the user the ability to capture two images and use the interline chip’s electronic shutter feature between images so that no signal is integrated in the time between[...]

Appendix H DIF Camera 101 Tips and Tricks Lab Illumination In DIF measurements, it is necessary to remain m indful of the possibility of laboratory light affecting the images. Because the first im age can be tim ed with precision, laboratory light that reaches the camera would generally not be a problem in the first image, particularly if the captu[...]
