…in lasers for machine vision,
in general?
Gutiérrez: Price, power, robustness
(temperature, hard environments), quality
(low speckle, uniformity).
Tremblay: Certainly, as 3-D laser displacement sensors become easier to use
and deploy, we'll see increased use of

…optics (see
Fig. 3). And in some cases, they require an
engine in which the coherence of the laser
is eliminated in order to avoid speckle and
ensure uniform stable illumination.
Partnering. As a result of these market
characteristics, instrument developers
and…

…and that was focused into
a disk of sapphire to generate a white
light continuum. I noticed that this
white light exhibited speckle and was
hence spatially coherent. I was hoping
that the process might be fully coherent
while covering a huge range of the electromagnetic…

observed membrane-localized MerMAID6 expression, with
some fraction of the protein displaying a speckled cellular distribution (Fig. 5a). However, illumination triggered high transmembrane photocurrents with biophysical properties similar to
those…
