本研究延續第一代焦散成像設計方法，提出彩色焦散成像設計，除了有明暗變化更多了色彩資訊，提升建築照明的價值。本研究設計的彩色焦散成像是透過擋板將光源分成三通道光路，搭配紅、綠、藍彩色濾光片產生三道色光，並延續第一代設計方法，將色光折射到目標面上，進行色光疊加實現彩色焦散成像。本研究使用模擬軟體建立成像架構，在目標面上獲得模擬結果，並加工實體焦散物件放入實際光路中，產生實際彩色焦散成像。本研究在彩色焦散成像中規劃紅色、綠色、藍色、青色、洋紅色、黃色、白色等7個色塊，探討模擬與實際成像中色度差異。計算結果顯示色度差異變化劇烈，本研究提出目標面上三通道的雜散光與光斑偏移，將會影響實際成像量測色度數值觀點，並針對觀點逐步驗證，最後得出實體焦散物件在拋光時，因焦散單元拋光凹痕，產生雜散光與光斑偏移，造成實際量測與模擬有巨大的色度差異，提供未來使用三通道光路架構，產生實際彩色焦散成像的研究，提供修正參考方向。

This research continues the first-generation caustics design method, and proposes a color caustics design. In addition to changes in light and shade, more color information is provided to enhance the value of architectural lighting.
The color caustic designed in this research is to divide the light source into three-channel light paths through a baffle, and use red, green, and blue color filters to generate three colored lights, and continue the first-generation design method to refract the colored lights to the target surface. Perform color light superposition to achieve color caustics. This research uses simulation software to establish the imaging framework, obtains the simulation results on the target surface, and processes the solid caustic objects into the actual light path to produce actual color caustics.
In this research, 7 color blocks of red, green, blue, cyan, magenta, yellow, and white are planned in color caustics, and the difference in chromaticity between simulation and actual imaging is discussed.
The calculation results show that the chromaticity difference changes drastically. This study proposes that the three-channel stray light and spot offset on the target surface will affect the actual imaging measurement chromaticity value view, and gradually verify the view, and finally obtain a solid caustic object During polishing, stray light and spot deviation are generated due to the polishing dents of the caustic cell, resulting in a huge chromaticity difference between actual measurement and simulation. It provides future research on using three-channel optical path architecture to produce actual color caustics. Provide correction reference direction.
