Abstract
An imager obtains and projects a vein image onto a patient and includes: an infrared laser; visible light laser; x-mirror; x-mirror driver; y-mirror; y-mirror driver; field programmable gate array (FPGA); photodiode; and front end circuit. The FPGA controls the lasers, x-mirror driver, and y-mirror driver to control the x-mirror and y-mirror to scan the light, and receives feedback of a state of the lasers, forming a closed control loop. The photodiode converts the reflected infrared vein image into an analog signal, which is processed by the FPGA including: performing an X-direction sum of pixel data for a plurality of boundary windows and placing it into an X-sum buffer, performing a Y-direction sum of pixel data and placing it into a Y-sum buffer, and using a total sum generator to obtain box filter output for each of the plurality of windows, being the X-sum buffer added to the Y-sum buffer.
