A 0.18 μm process CMOS image sensor has recently been developed by e2v technologies plc. with a 0.5 megapixel imaging area consisting of 6 × 6 μm 5T pixels. The sensor is able to provide high performance in a diverse range of applications including machine vision and medical imaging, offering good low-light performance at a video rate of up to 60 fps. The CMOS sensor has desirable characteristi...

This paper addresses the development of a micropower 176 x 144 CMOS active pixel image sensor that dissipates one-to-two orders of magnitude less power than current state of the art CMOS image sensors. The chip operates from a 1.5 V voltage source and the power consumption measured for the chip running from an internal 25.2 MHz clock yielding 30 frames per second is about 550 μW. This amount en...

Multi-beam confocal microscopy without any physical pinhole was demonstrated. As a key device, a custom CMOS image sensor realizing a focal-plane pinhole array effect by special pixel addressing and discarding of the unwanted photocarriers was developed. The axial resolution in the confocal mode measured by FWHM for a planar mirror was 8.9 μm, which showed that the confocality has been achieved...
