In this detection scheme a conventional scanning sample or laser-scanning transmission microscope is employed.
Numbers vary depending on the detection scheme and research demographics.
Although single-element transducers have been employed in these two systems, the detection scheme can be extended to using ultrasound arrays as well.
The geometry is also amenable to deployment for short-pulse laser, single-molecule detection schemes.
Despite the apparent rarity of these events, observation of the intense maser emission has been suggested as a detection scheme for extrasolar planets.
"It's not only consistent with the land-based detection schemes, but it doesn't suffer from the problems of being clouded by the noise that critics always focus on."
Experts say they understand the public's appetite for new early detection schemes, but worry that unscrupulous practitioners may exploit patients' fears in the interest of their own profit.
This phenomenon also has detrimental effect on moving target indicator systems, where the detection scheme subtracts signals received from two or more transmit pulses.
Pulse-Doppler radar systems compensate using 3 or more different pulse repetition frequency in the detection scheme.
Medium PRF has unique radar scalloping issues that require redundant detection schemes.
