ROJDESTVENSKIY Dmitriy Sergeevich (7. 4. 1876, Peterburg — 25. 6. 1940, Leningrad), fiziki soveti, yake az asosguzoroni sanoati optiki dar SSSR, akad. AF SSSR (1929, azo-korr. 1925). Unstituti Peterburgro khatm namud (1900). So¬li 1901 tahsilro dar Leypsing va Gisen davom dod. Az soli 1903 dar Universiteti Peterburg kor kard (az soli 1916 professori). Dar hamin universitet shubai fizikaro tashkil namuda, dar talimi fizika navigariho jori namud. Bo tashabbusi Rojdenstvenskiy soli 1918 instituti davlatii optika tasis yoft, ki Rojdenstvenskiy to soli 1932 direk¬tor va rohbari ilmii on bud. Dispersiyai anomaliro dar bughoi nat¬riy tadqiq kard va usuli muayyan kardani dispersiyai anomalii miqdoriro kashf namud (1910). In kashfiyoti Rojdenstvenskiy baroi omukhtani disper¬siyai anomali dar bughoi metallhoi gunogun istifoda shud va dar natija doir ba intensiviyati khathoi spektri va sokhti atom malumothoi muhim girifta shud. Minbad Rojdenstvenskiy in usulro baroi omukhtani disper¬siyai anomali dar bughoi metallhoi dushvorgudoz tatbiq namud. Baroi in u kurai vakumiro, ki dar on harorat to 30000S merasid, istifoda burd. Rojdenstvenskiy ba korkardi nazariya in tasnifi spektrhoi atomi sahmi ka¬lon guzosht, nakhustii aqidaro oid ba tabiati magnitii dubletho va triplethoi spektri pesh nihod. Solhoi 1939—1940 yak qator korhoro oid ba nazariyai mikroskop yadro namud, ba roli muhimi intorferensiya hangomi paydoshavii tavsir dar mik¬roskop baho dod. Maktabi olimon- optikhoi SSSR-ro ba vujud ovardaast.
