This paper discusses a high speed image sensor, manufactured in a 180nm CMOS process. The sensor has a unique combination of large format, a 2560x2560 array of 6um pixels, high-speed read-out, and a linear single exposure dynamic range of 98dB. The dual gain pixel operates in overflow mode achieving a noise floor of 4.75eover a 375kefull-well charge. The(More)
In the Flemish horticulture Pythium spp. is an important pathogen of tomato plants (Lycopersicon esculenthum) in soilless growing media. Therefore some experiments were conducted to evaluate the possibility of decreasing the damage caused by Pythium spp. by Trichoderma spp. In a tray with several growing media, a suspension of Trichoderma conidia (10(6)/ml(More)
Numbers of strains of Trichoderma asperellum are known as biological control agents of certain root pathogens of tomato (Lycopersicon esculentum). The restricted use of fungicides is sometimes useful in combination with these biological control agents. Therefore some experiments were conducted to evaluate the growth of T. asperellum in the presence of(More)
An experiment was conducted to evaluate the distribution of T. harzianum in soilless media used in greenhouse growing systems for tomatoes. Growing media based on rockwool and based on coconut fibre were included. The fungus was applied to the roots of the plant by means of a conidial suspension. The upper plant parts were removed from the coconut fibre an(More)
This paper presents a high speed CMOS image sensor design targeting various industrial applications. Targetted for a 0.18 um CMOS process, the sensor captures frames at 1000fps at the target resolution of 5 Megapixel and supports rolling and global shutter modes. The sensor design has 4480, 14-bit column A/D converters, supporting a line rate of >2.2(More)
