*Pinpoint precision: the Light Processing Unit (LPU) maintains a uniform, high density laser spot
to ensure accurate, repeatable prints.
This Will Ideally Be Achieved Through Sub 20Micron Layers And Sub 40Micron Laser Spot
Instead of creating the riblet grooves with one focused laser spot
'line by line', 4JET says it has now found a way to speed up the process by a factor of about 500 using the principle of laser interference patterning.
The dotted line parallel to the laser beam means that when the object is at infinitely distant from the radar, the reflected laser spot
just falls on the edge of the CMOS sensor, which means when we measure objects at infinity, the laser spot
falls on one end of the image; while at the smallest ranging distance [q.sub.min], the laser spot
falls on the other end of the image.
where: R is the radius of laser spot
; [q.sub.max] is maximum power density of laser irradiation, with [q.sub.max] = 2[q.sub.0]/(1-[e.sup.-2]), [q.sub.0] is average power density.
The laser power was gradually increased until it formed a faint laser spot
. The power of the micropulse pattern laser was set at 50% of the power needed to form a barely visible laser spot
Variable control of laser spot
diameters (from 0.4 to 8.5 mm) increases efficiency and resolution, according to the company.
The optical microscope is used for locating the laser spot
on the cantilever and positioning the sample.
Upon increase of the irradiation power from 5 x [10.sup.4] to 8 x [10.sup.4] W/[cm.sup.2] and related increase of the sample's local temperature within the laser spot
, the value of the parameter [X.sub.c] grew markedly slower (~40% total growth) than that of the parameter L (~230% total growth).
The navigated photocoagulation seems to demonstrate a higher laser spot
application accuracy in focal laser therapy of DME than conventional laser technique.
The shortage of the bisected laser-based auto-focusing method is that when the defocus is small, serious diffraction effects make the detected laser spot
an irregular round spot.
The centroids of the resulting images (Figures 1(b), 1(d), and 1(f)) were calculated, and a model created to relate the centroid position of the laser spot
with the distance from the ablation site.
