Optical imaging using binary sensors

Optical imaging using binary sensors.

This paper addresses the problem of reconstructing an image from 1-bit-quantized measurements, considering a simple but nonconventional optical acquisition model. Following a compressed-sensing design, a known pseudo-random phase-shifting mask is introduced at the aperture of the optical system. The associated reconstruction algorithm is tailored to this mask. Our results demonstrate the feasib...

Weight Measurements by Using Simple Optical-Fiber Sensors (RESEARCH NOTE)

The use of different optical-fiber sensors for weighing measurements is Abstract described. By using three different mechanical stressing mechanisms, the operation of the fiber-to-fiber transducer systems are tested and the results are presented. Parameters such as sensitivity, hysteresis, resolution, and dynamic range are measured. A comparison of the results has shown that the sensor system m...

System identification using binary sensors

System identification is investigated for plants that are equipped with only binary-valued sensors. Optimal identification errors, time complexity, optimal input design, and impact of disturbances and unmodeled dynamics on identification accuracy and complexity are examined in both stochastic and deterministic information frameworks. It is revealed that binary sensors impose fundamental limitat...

Secure Detection Using Binary Sensors

Cyber-physical systems employing remote sensors and actuators and sparse communication networks are pervading the infrastructure. In this paper we consider a prototypical problem of estimating a binary state using measurements provided by binary sensors. We propose a new approach to estimate the states based on sensor measurements that may have been corrupted by an attacker. The problem is form...
