Розглянуто типи лазерних проекційних систем та охарактеризовано основні технології відтворення зображення. Проведено аналіз методів зниження спеклових шумів у лазерних проекторах. На основі аналізу способів декореляції лазерних променів запропоновано класифікацію методів зменшення когерентних шумів, визначено основні переваги методів і їхні недоліки. Показано, що активні методи зниження спеклових шумів є найбільш ефективними.Посилання
