Kunyora Laser pasi pevhuKristaro yeScintillation
Imwe nzira ndeyekushandisamatekiniki ekugadzira laser pasi pevhu (SSLE)yemakristaro escintillator.
Nekutarisa laser mukati mekristaro, kupisa kunogadzirwainogona kugadzira maitiro akadzorwa ema microcracksizvozvinoshanda semaumbirwo anoratidzira, kugadzira zvinobudiriramapikisheni anotungamira chiedzapasina chikonzero chekuparadzana panyama.

2. Hunhu hwemaziso uye geometry yezvimiro zvinoratidza zvinogonakudzorwa kwakarurama, zvichiita kuti pave nekugadzirwa kwemaumbirwo nemasaizi epikiseli akagadzirwa.
3. Kuverenga nekuvhura magadzirirwo ekuona zvinhuinoramba yakafanana neyema pixelated arrays akajairwa.
