З метою отримання малогабаритної компактної безспеклової пасивної лазерної проекційної системи, що забезпечує однорідне освітлення, проведено теоретико-математичний аналіз механізмів зменшення суб’єк-тивних спеклів, який показав, що досягнення цієї мети вимагає одночас-ного зменшення часової і просторової когерентності лазерного пучка та маніпулювання з його поляризацією. В результаті цього дослідження запропоновано пасивну оптичну схему, що заснована на ефекті некогерентного фокусування лазерного пучка проектора, яка дозволяє утворити безспеклову прямокутну рівномірно освіт-лену пляму на шорсткому екрані. Система передбачає деполяризацію лазерного пучка та наявність оптичного дифракційного елемента (ДОЕ) на основі псевдовипадкової бінарної послідовності, що утворює ефект згладжування. Також передбачено, що ця система може бути утворена з наявних лазерних джерел світла і оптичних елементів. Експериментально верифіковано принцип роботи такої системи.
