They also would also provide lower performance than a microbolometer array.Ben Krasnowhttps://www.blogger.com/profile/04234629396863486242noreply@blogger.comtag:blogger.com,1999:blog-401164737462963207.post-64251442083980273742011-12-08T06:53:55.028-08:002011-12-08T06:53:55.028-08:00There are IR sensors that contain array of pixels....There are IR sensors that contain array of pixels.

It seems that you have all of the bits for a good TIS. i am sure that you thought of cooling the sensor with LN2 It will be interesting to see your test results at a much lower temp. <br />Thanks, ron Cheers.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-401164737462963207.post-53492426889356673012011-08-01T13:50:20.855-07:002011-08-01T13:50:20.855-07:00That's really exciting project.

To make it work, you have to open the project in quartus and go to (Assignments->Device) to select your specific fpga device and also (Assignments->Pin Planner) to change the pins for the 50mhz clock input and VGA output(vsync,hsync,green) (look on page 37/38 on this doc: http://www.terasic.com.tw/cgi-bin/page/archive_download.pl?Language=English&No=83&FID=91d2cf46f90973377b1f71bd42040740) only one bit monochrome so use the pin for green[3]<br /><br />Tell me if it works:)<br />Simon<br />http://dr.kerker.zuliah.com/vga_monitor_codepage.zipSimonnoreply@blogger.comtag:blogger.com,1999:blog-401164737462963207.post-42041176228407063432011-07-25T05:46:20.589-07:002011-07-25T05:46:20.589-07:00Is there any microprocessor involved in this syste...Is there any microprocessor involved in this system?hire magento developerhttp://www.hire-web-developers.com/Hire-Magento-Developer.htmlnoreply@blogger.com
