The alleged 'flying spot
TV ophthalmoscope', enabled ophthalmologists with an alternate method of taking pictures of the fundus.6 SLO uses a series of vertical and horizontal scanning mirrors to inspect a particular region of the retina with a single point of laser light at a specified wavelength which display raster images on a television monitor.
In this paper we discuss how the x-ray backscatter systems produce images, and in that light we quantify the accuracy of the recommended dosimetric methods when applied to the metrology of a "flying spot" of x rays.
The integral of the scattered signal is assigned to a pixel value in a two-dimensional image corresponding to the transient location of the flying spot. In the case of the backscattered image, the x rays that reach the detector have mostly passed through any clothing and have scattered from the near surface of the skin or from objects on the body of the person being scanned.
First, there is no "concentration" of the x-ray beam in either time or space; for many purposes, the metrology of a flying spot can be viewed as the metrology of a moving aperture in front of a conventional x-ray source, albeit in motion itself.

The SPS-2301 flying spot
measurement sensor/controller combination is said to allow users to custom program job profile settings of surfaces with various reflectivities.
The MSI G2X scanner uses a "flying spot
laser triangulation" measurement method, optical scanning technology that enables it to detect and record every coordinate point along the surface of the part with nearly zero information loss or image distortion.
"Our advanced flying spot Technolas 217 Excimer Laser System is the technology leader around the world, and we intend to make it a leader in the U.S.
The Technolas 217 goes a step beyond the current standard of broad beam (about a 6mm diameter) technology, creating a new therapeutic approach with a scanner-directed 2mm flying spot beam.
McDonald, MD, moderated the news conference, and spoke on the use of the "flying spot
" excimer laser in conjunction with corneal topography and wavefront imaging tracking systems to more precisely customize corneas for the correction of nearsightedness.
Microscopists have understood the advantages of a "flying spot
microscope" since the early 1950s.
The flying spot
measurement sensor and controller combination is said to allow users to custom program targets with widely varying geometries.
