These sources have been complemented by beam delivery systems, either based on ultrafast scanners or some special diffractive optical elements (DOE), that spread one beam into a pattern of many identical beamlets.

It is noted that besides image filtering methods, there are many other potential algorithms used for crack detection investigated by various scholars; these algorithms include wavelet transform [18], beamlet transform [19], wavelet-morphology-based detection [20], weighted neighborhood segmentation [21], deep learning [2, 22-24], fuzzy Hough transform [25], probabilistic generative model [7], and optimized minimal path selection [5].

"For petawatt laser capabilities, funding of $5,000,000 is provided to modify the beamlet laser at the Sandia national laboratories and $1,000,000 is provided for technical community activities in developing critical short-pulse, high power laser technology.

In its first try as a Sandia National Laboratories diagnostic tool, the third-biggest laser on earth, Z Beamlet, confirmed that Sandia's Z machine--the most powerful laboratory producer of X-rays in the world--spherically compressed a simulated fusion pellet during a firing, or "shot," of the giant accelerator.

Additionally the electron beam will be treated as charge rings or beamlets [7] to account for their transversal trajectories.

The oncologist wouldn't make a decision based on the intensities of beamlets, but rather on the dose deposited in the patient's body.

Because the radiation source rotates around the patient, moving at an unparalleled speed of 250 cm/second, the radiation is delivered with extreme precision using tens of thousands of tiny "beamlets." This allows treatments that are difficult for conventional radiotherapy machines to deliver such as treating just the lining of the lung and not the lung itself or treating around the spinal cord but not the spinal cord.

Conceptually, an intensity-modulated beam in IMRT can be considered to consist of hundreds of tiny beamlets that have different intensities (Figure 7).
