ASIC Test System
A production automated test system for functional testing of custom integrated circuits.
Generates user defined high-speed digital input patterns, while recording and analyzing high-speed digital and analog outputs for correct timing and amplitude. Also includes report generation and data output to file and image formats.
The screenshot below shows a setup screen that allows operators to control the timing of the applied pulses.
In biological imaging, the object of interest is not always in plain sight. This is especially true when trying to image cells buried deep within tissues. The tissues covering the cells tend to bend and scatter the light passing through them, preventing sharp images of the cells within. To overcome this, researchers at the Howard Hughes Medical Institute thought of a novel way to use adaptive optics.
Adaptive optics is a technique used to correct for imaging aberrations. It is most famously known in astronomy where ground-based telescopes correct for how the atmosphere tends to bend and scatter starlight. In the case of biological microscopy, the technique can be adapted to correct for the biological aberrations. Here many images are initially taken to characterize the aberrations that each light path through the sample experiences. A spatial light modulator is then used to steer the parts of the light beam back into sharp focus. To develop the instrument control program to carry out this technique, the researchers worked with Dr. Daniel Milkie of Coleman Technologies to build the LabVIEW program that would run the 2-photon microscope, analyze the images, and optimize the adaptive optics to correct the aberrations. This success of this work was recently published in Nature Methods. Nature Methods Article Abstract
