With media of very high optical density the light intensity available in the transmittance mode may be insufficient compared to the electrical noise of the photodetector and reflectance is then the mode of choic
The absorbance of a homogeneously doped laser crystal, for example, is proportional to its length and the doping concentration.An alternative term, which however is ambiguous, is optical density.Absorbance values often depend on the optical wavelength....

Giant optical transmittance changes of over 300% in wide wavelength range from 500nm to 2500nm were observed in LaBaCo 2 O 5.5+ thin films annealed in air and ethanol ambient, respectively. The reduction process induces high density of ordered oxygen vacancies and the formation of LaBaCo 2 O...
We Need to Estimate Transmittance! 在离线渲染中,为了保证无偏性,我们通常进行蒙特卡洛估计(后简称MC)。一种经典的方式就是先通过Russian Roulette(RR): \hat L= \begin{cases} \frac{1}{q}T_r(p_s\rightarrow p)L_o(p_s,-w) & u\in[0,q)\\ \frac{1}{1-q}\int_0^{t_s} T_r(p'\ri...
It is extremely difficult to measure the transmittance of objects that are not flat. Optical lenses are especially difficult to measure. This is because the curvature of the object deflects the beam of light passing through the object. A diffuse transmittance measurement may work if the object’...
However, it is quite common to see units of AU stated after the absorbance which are to said to either stand for arbitrary units or absorbance units. These units are redundant and should be avoided. Another common encounter is the use of the term optical density or OD in place of ...

The density is about 2.0 J/cm2 at 5 Hz. After finishing the growth of the LBCO thin film, it was annealed at 700 °C for 15 min in pure oxygen (200 Torr), then cooled down to room temperature at the rate of 30 °C/min. Structural, electrical and optical ...
