摘      要：Corner cube retroreflectors(CCRs)have applications in sensors,image processing,free space communication and wireless *** ability to construct low-loss wavelength filters embedded in CCRs can enable the development of wavelength multiplexing,tunable lasers and photonic integrated *** we created an~10-μm-thick holographic corner cube retroreflector(HCCR)array that acted as a color-selective wavelength filter and diffracted light at broad ***-resolved spectral measurements showed that the Bragg peak of the diffracted light from the HCCR array could be tuned from 460 to 545 nm by varying the incident *** HCCR array also exhibited a wavelength-selective tuning capability based on the rotation angle in the visible *** projected holographic images with the rotational property in the far *** utility of the HCCR was demonstrated as optical temperature and relative humidity sensors that produced a visible colorimetric response for rapid diagnostics.
