Final answer:
Optical stimulated detectors are used in astronomy to take long exposure photographs of celestial objects and in medical procedures like LASIK to correct vision. These detectors can also be part of personal dosimeters, worn to measure radiation exposure over time.
Step-by-step explanation:
An optical stimulated detector refers to a device used for detecting light or photons, often utilized in various technological and scientific applications such as astronomical observations and medical procedures like LASIK surgery.
In astronomy, the integration time of such detectors allows for long exposures which are essential for capturing images of very faint astronomical objects. These exposures can last for several hours to accumulate enough light energy to produce a significant image.
In medical applications, specifically LASIK eye surgery, an intense light with a very pure wavelength is used to remove corneal tissue with high precision.
This light is emitted in bursts to reshape the cornea and correct vision impairments such as nearsightedness, farsightedness, and astigmatism. The wavelength used is strongly absorbed by the corneal tissue, enabling precise evaporation and allowing the eye to heal rapidly after the procedure.
Moreover, optical stimulated detectors can also be part of personal dosimetry systems, used to measure exposure to ionizing radiation and ensure safety for individuals working in radiation environments. These devices, like electronic personal dosimeters, are worn and measure the effective dose of radiation received over a period.
