IPC Classification: G02F 1/00
Abstract:
Existing visibility measuring devices are complex in construction and they dont have simple electronic system. In these devices, the  real time response of main system is dependent on various sub systems performance. Also performance of these devices depends on  too many sub systems for a comprehensive accuracy. The present invention discloses a visibility measuring device having a  acclimated light beam generator and an analyzer using onto-mechanical elements. The device is capable of full scale operation (10 to  > 10000 meters) with minimum light intensity of 0.33 lumen and can be installed either parallel to runway in an airport or parallel to  road. Device acquires continuous visibility data from field-site, which is transmitted in dual mode communication protocol viz.,  landline and Wi-Fi, throughout the year withstanding harsh environmental situations like fog, sandstorm, rain and extreme hot weather  conditions. This cost effective device of present invention ensures uninterrupted, reliable visual guidance for the pilots at Airports and  for safety of the travelers on the road.
Startup Options:
a)Visibility measuring device for low and high visibility condition. B)The device requires one simple single analog electronic card having least part count. c)It has minimal power consumption. d) The device is simple, easy and inexpensive. e)No sophisticated and costly equipments involved for installation and commissioning. f) It requires short time to install the device and eliminates a need for maintenance of high level expertise in a field. g) It is useful for measuring visible range in meters, communicates the device to air traffic control room for reporting to pilots. h)It is useful for measuring visible range in meters for daylight, twilight and night time.
