  • Publication number: 20210396662
    Abstract: Provided is a method for predicting optical properties of a sample, the method including obtaining, by a device, a plurality of diffuse reflectance values based on optical energy diffusely reflected from the sample, generating, by a multi-layered Deep Fully Connected Neural Network (DFCNN) in the device, a first set of intermediate values by non-linearly mapping the plurality of diffuse reflectance values to the first set of intermediate values, generating, by a One-Dimensional-Convolutional Neural Network (1D-CNN) in the device, a second set of intermediate values by non-linearly mapping the plurality of diffuse reflectance values to the second set of intermediate values, and predicting, by the device, values of the optical properties of the sample based on the first set of intermediate values and the second set of intermediate values.

  • Publication number: 20210302310
    Abstract: A method of transforming Monte Carlo (MC) simulations for diffuse reflectance spectroscopy (DRS) may include obtaining, by a DRS device, MC simulated DRS measurements using a pre-defined number of photons; pre-processing, by the DRS device, the MC simulated DRS measurements to obtain normalized DRS measurements; correcting, by the DRS device, non-monotonicity of the normalized DRS measurements to obtain monotonic DRS measurements; converting, by the DRS device, the monotonic DRS measurements to a logarithmic domain to obtain logarithmic DRS measurements; performing, by the DRS device, curve fitting on the logarithmic DRS measurements in the logarithmic domain to obtain curve-fitted logarithmic DRS measurements; and transforming, by the DRS device, the curve-fitted logarithmic DRS measurements to a non-logarithmic domain to obtain transformed MC simulated DRS measurements.
