Nā loina o ke ana
Ke hoʻomālamalama ka kukuna i ka electrode, e hoʻopili ʻia ka kukuna, hōʻike ʻia a hoʻopuehu ʻia e ka electrode, e hopena i kekahi attenuation o ka ikaika o ka ray ma hope o ka electrode i hoʻouna ʻia e pili ana i ka ikaika o ka hihi hanana, a ʻo kona attenuation ratio he negatively exponential me ke kaumaha a i ʻole ka ʻāpana ākea o ka electrode.
I=I_0 e^−λm⇒m= 1/λln(I_0/I)
I_0 : Ka ikaika kukuna mua
I: Ka ikaika o ka ray ma hope o ka lawe ʻana i ka electrode
λ : Ka helu ʻana o ka mea i ana ʻia
m : Mānoanoa/areal mānoanoa o ana mea
Mea koʻikoʻi
Ka hoʻohālikelike ʻana o ka ʻike semiconductor a me ke ana ʻana i ka ʻike laser
● Ana o ka kiko'ī outline a me nā hiʻona: millimeter spatial resolution areal density outline ana me kiʻekiʻe-wikiwiki a kiʻekiʻe-pololei (60 m/min)
● Ana laulā ultra: hiki ke hoʻololi i ka ʻoi aku ma mua o 1600 mm laula o ka uhi.
● Ka nānā 'ana i ka māmā ki'eki'e: 0-60 m/min hiki ke ho'ololi.
● Mea ʻike uila semiconductor hou no ke ana electrode: 10 manawa ʻoi aku ka wikiwiki o ka pane ʻana ma mua o nā hoʻonā kuʻuna.
● Hoʻoulu ʻia e ka mīkini laina me ka wikiwiki a me ka pololei kiʻekiʻe: hoʻonui ʻia ka wikiwiki scanning e 3-4 mau manawa i hoʻohālikelike ʻia me nā hoʻonā kuʻuna.
● Hoʻomohala ʻia nā kaʻa kaʻa kaʻa kiʻekiʻe kiʻekiʻe: sampling frequency a hiki i 200kHZ, e hoʻomaikaʻi ana i ka pono a me ka pololei o ka uhi pani pani.
● Ka helu ʻana o ka hiki ke hoʻemi ʻia: hiki ke piʻi i ka 1 mm liʻiliʻi ka laulā kiko. Hiki iā ia ke ana pololei i nā hiʻohiʻona kikoʻī e like me nā outlines o ka ʻāpana lahilahi a me nā ʻōpala i ka uhi o ka electrode.
