Co je sv\u011bteln\u00fd sn\u00edma\u010d<\/h2>\n\n\n

Sv\u011bteln\u00fd sn\u00edma\u010d, zn\u00e1m\u00fd tak\u00e9 jako fotosn\u00edma\u010d nebo fotoelektrick\u00fd sn\u00edma\u010d, je za\u0159\u00edzen\u00ed, kter\u00e9 detekuje a m\u011b\u0159\u00ed p\u0159\u00edtomnost nebo absenci sv\u011btla. Jedn\u00e1 se o fotoelektrick\u00fd p\u0159\u00edstroj, kter\u00fd p\u0159em\u011b\u0148uje sv\u011btelnou energii neboli fotony od infra\u010derven\u00e9ho po ultrafialov\u00e9 spektrum na elektrick\u00fd sign\u00e1l, obvykle ve form\u011b elektron\u016f. Sv\u011bteln\u00fd sn\u00edma\u010d generuje v\u00fdstupn\u00ed elektrick\u00fd sign\u00e1l, kter\u00fd odpov\u00edd\u00e1 vstupn\u00ed sv\u011bteln\u00e9 energii.<\/p>\n\n\n\n

Sv\u011bteln\u00e9 sn\u00edma\u010de funguj\u00ed na principu fotoelektrick\u00e9ho jevu, kdy ur\u010dit\u00e9 materi\u00e1ly p\u0159i vystaven\u00ed sv\u011btlu vyza\u0159uj\u00ed elektrony. Tento jev vyu\u017e\u00edvaj\u00ed k detekci a m\u011b\u0159en\u00ed sv\u011btla. Sv\u011bteln\u00e9 sn\u00edma\u010de pou\u017e\u00edvaj\u00ed fotocitliv\u00fd materi\u00e1l, jako je fotodioda nebo fototranzistor, kter\u00fd p\u0159i vystaven\u00ed sv\u011btlu generuje elektrick\u00fd proud. Intenzita sv\u011btla ur\u010duje velikost vygenerovan\u00e9ho proudu.<\/p>\n
