A device may receive spectroscopic data associated with a dynamic process. The device may identify a pseudo steady state end point based on the spectroscopic data. The pseudo steady state end point may indicate an end of a pseudo steady state associated with the dynamic process. The device may identify a reference block and a test block based on the pseudo steady state end point, and may generate a raw detection signal associated with the reference block and a raw detection signal associated with the test block. The device may generate an averaged statistical detection signal based on the raw detection signal associated with the reference block and the raw detection signal associated with the test block, and may determine whether the dynamic process has reached a steady state based on the averaged statistical detection signal.

Dynamic process end point detection

In some implementations, a device may identify, based on spectroscopic data, a pseudo steady state end point indicating an end of a pseudo steady state associated with the blending process. The device may identify a reference block and a test block from the spectroscopic data based on the pseudo steady state end point. The device may generate a raw detection signal associated with the reference block and a raw detection signal associated with the test block. The device may generate a statistical detection signal based on the raw detection signal associated with the reference block and the raw detection signal associated with the test block. The device may determine whether the blending process has reached a steady state based on the statistical detection signal.

Blending process end point detection

An optical device may comprise an array of sensor elements that includes a plurality of pixels and a multispectral filter disposed on the array of sensor elements. The multispectral filter may be configured to pass a first transmission percentage of light of a particular spectral range to a first set of pixels of the plurality of pixels and pass a second transmission percentage of light of the particular spectral range to a second set of pixels of the plurality of pixels.

Multispectral filter

An optical device may include a plurality of sensor elements and a plurality of optical channels. The plurality of sensor elements may include a first set of sensor elements associated with a first wavelength range and a second set of sensor elements associated with a second wavelength range. The plurality of optical channels may include a first set of optical channels associated with the first wavelength range and a second set of optical channels associated with the second wavelength range. A first optical channel, of the first set of optical channels, may be disposed over a first sensor element, of the first set of sensor elements, and a second optical channel, of the second set of optical channels, may be disposed over a second sensor element, of the second set of sensor elements.
