Therefore, by definition, δE/δω δ E / δ ω is L L, the radiance. Thus L = B L = B. We see, then, that radiance L L and surface brightness B B are one and the same thing. Henceforth we can use the one term radiance and the one symbol L L for either, and either definition will suffice to define radiance. FIGURE I.1 FIGURE I.1.

Steradian is an exploration of the geometric genre and although it has a geometric base, the widths between letters are not much different across the weights, something common of the style. That is due to the process, in which the proportions of the heavier weights paved the way for the lighter ones. It also has a series of details that make ...1 steradian has a surface area of 1m^2 at a range of 1m, 4m^2 at 2m, 100m^2 at 10m, 0.01m^2 at 0.1m, etc. So assuming there are no additional optics, the irradiance at distance D metres will be 3/D^2 W/m^2 for your 3W/sr source. To take a step back though, you get roughly 1.5kW/m^2 irradiance from the sun.스테라디안(steradian, 기호 sr)은 입체각의 국제 단위이다. 평면에서 각도를 나타내는 라디안처럼, 3차원 공간에서 각도로 나타나는 2차원의 영역을 나타낼때 사용된다.Steradian is a unit of measurement for the solid angles.
