period of time during a sterilization or disinfection process in which items are exposed to the sterilant or disinfectant at the parameters specificed by the manufacturer (e.g., time, concentration, temperature, pressure)
Duration of the process of exposing a recording medium to radiation.
The exposure time determines how long light is allowed to pass through the lens into the camera. This is usually measured in fractions of a second. Within this space of time, the film or sensor is exposed to light, resulting in a picture.
Time during which the target is observed plus, in the case of chopped observations, the time for measurements at a reference position.
The time that the "shutter" on the telescope instrument is open. The longer the exposure time, the fainter the things that can be seen. Exposure times on professional telescopes can be anywhere from tiny fractions of a second for studying bright stars to many hours when hunting for very faint objects.
Length of time the CCD is accumulating charge; in CAMTESTâ„¢, a software setting that determines the length of time the CCD is accumulating charge but does not include the time the shutter is opening or closing. In CCD camera technology, the length of time for a full parallel shift sequence to occur.
Length of time a test organism is exposed to a test solution.
The length of time a specific mail-in device must be in contact with radon or radon decay products to get an accurate radon measurement. Also called exposure period, exposure parameters, or duration of exposure.
The time during which the sensor is exposed. In the case of a sensor with an electronic shutter, the shutter speed is the time for which the shutter is held open during the taking of an image and this may be shorter time than the actual frame period.
(1) The length of time that a CCD is accumulating charge. (2) In many software programs, the name for the setting that determines the length of time that a CCD is accumulating charge. excess noise factor - The statistical nature of the multiplication gain in EMCCDs results in excess noise in the output signal. Typically it is between 1.2 to 1,4. For more information, refer to on-chip multiplication gain tech note.
