Photons produced in the hard scattering of partons, named prompt photons, provide information about the internal structure of hadrons. The NICA collider has the possibility to provide new data to study the production of prompt photons in non-polarized and polarized proton-proton collisions, which gives an access to spin-dependent parton distribution functions for gluons. Unpolarized and polarized physics with prompt photons and capabilities of the SPD detector in such measurements is discussed., Фотони, утворенi в жорсткому розсiяннi партонiв, так званi миттєвi фотони, дають iнформацiю про внутрiшню структуру адронiв. Колайдер NICA зможе забезпечити новi данi про народження миттєвих фотонiв в неполяризованих та поляризованих процесах фотонарождення, що, в свою чергу, дасть iнформацiю про спiновi функцiї розподiлу глюонiв. В данiй статтi представлено фiзику поляризацiї iз миттєвими фотонами i можливостi детектора SPD в таких експериментах.
