تشعشع3 - فاطمه رمضانی - 15-08-2020 رابطه شدت تشعشع با گسیل آنویرایش با توجه به شکل بالا اکنون مفهوم آهنگ تشعشع گسیل شده را بر حسب شدت طیفی تشعشع گسیل شده بیان می‌کنیم. شدت طیفی تشعشع گسیل شده عبارت است از آهنگ تشعشعی که با طول موج λ {\displaystyle \lambda } در امتداد ( θ , ϕ ) {\displaystyle (\theta ,\phi )} از مساحت واحد سطح گسیلنده‌ای که عمود بر امتداد مذکور قرار دارد به داخل ناحیه متناظر با زاویه فضایی واحد در بازه d λ {\displaystyle d\lambda } حول آن گسیل می‌شود. توجه کنید که سطحی که در این تعریف استفاده می‌شود تصویر سطح d A 1 {\displaystyle d{{A}_{1}}} در امتداد عمود بر تشعشع است. یعنی d A 1 cos ⁡ θ {\displaystyle d{{A}_{1}}\cos \theta } . بنابراین شدت طیفی برابر است با: I λ , e ( λ , θ , ϕ ) ≡ d q d A 1 cos ⁡ θ . d ω . d λ {\displaystyle {{I}_{\lambda ,e}}(\lambda ,\theta ,\phi )\equiv {\frac {dq}{d{{A}_{1}}\cos \theta .d\omega .d\lambda }}} و از آن آهنگ تشعشع گسیل شده از یک سطح بدست می‌آید: d q λ = I λ , e ( λ , θ , ϕ ) d A 1 cos ⁡ θ . d ω {\displaystyle d{{q}_{\lambda }}={{I}_{\lambda ,e}}(\lambda ,\theta ,\phi )d{{A}_{1}}\cos \theta .d\omega } همچنین شار تشعشع طیفی مربوط به سطح d A 1 {\displaystyle d{{A}_{1}}} می‌شود: d q  ″ λ = I λ , e ( λ , θ , ϕ ) cos ⁡ θ sin ⁡ θ d θ d ϕ {\displaystyle d{{q}^{''}}_{\lambda }={{I}_{\lambda ,e}}(\lambda ,\theta ,\phi )\cos \theta \sin \theta d\theta d\phi } با انتگرالگیری از این معادله می‌توان توان گسیل نیم کروی را بدست آورد.
