“…Optical encryption involves utilizing optical methods to implement various transformations or processes on input information [15][16][17][18][19], disrupting the wavefront or light intensity distribution of the original image through specific optical transformations to achieve image data encryption [20][21][22][23][24]. Currently, the common transformations in optical encryption systems include Fourier transform, fractional Fourier transform, Fresnel transform, Gyrator transform, and linear canonical transform.…”

Traditional encryption algorithms like DES suffer from the issue of key length (128 bits to 256 bits) and the inconvenience of memorization. Users typically store keys in a file or device, or even directly on a computer hard drive, releasing the key through a relatively easy-to-remember passphrase. Addressing these issues, this paper proposes a novel remote sensing image encryption system based on a hybrid model incorporating a 4D Lorenz chaotic system, Gyrator transform, Acousto-optic Conversion system, and dynamic DNA encoding. Firstly, the original image is scrambled using a 4D Lorenz mapping function. Subsequently, employing an Acousto-optic modulation algorithm, audio information is fitted into image information and serves as part of the encryption system key, significantly enhancing the correlation between the key and the user. Then, employing a dynamic DNA encoding algorithm, the image is encoded using eight different DNA encryption schemes and three distinct computational rules, achieving an exponential expansion of the key space with minimal computational overhead. Finally, through comparative analysis, the Gyrator transform, demonstrating superior performance, is selected to further encrypt remote sensing image data, expanding the key space. The proposed remote sensing image encryption system exhibits high security performance and robustness against various attacks.

“…In order to detect high frequency information, according Nyquist sampling theory, a high-frame rate camera is required which limits the maximum detectable frequency of the vibrating speckle pattern. To overcome this problem, several groups have turned to line array cameras [22][23][24][25][26][27][28], and single pixel detector methods [29] which can achieve higher sampling frequencies. The main drawback of these methods, however, are the difficulty of the alignment process making them unpractical.…”

In this paper, an innovative approach for detecting and analyzing speckle pattern signals is demonstrated, based on dynamic speckle analysis using a low-cost and low-framerate rolling shutter (RS) CMOS image sensor. The row scanning mechanism of a rolling shutter camera samples dynamic speckle patterns at a higher rate than typical Global Shutter (GS) cameras. In this research we demonstrate the detection and analysis of vibration signals that arise from an acoustic signal. We will illustrate the process of reconstructing a voice signal by analyzing a vibrating speckle pattern, with a primary focus on detecting and audibly capturing lung sounds.
