| titleOfInvention | RADIATION SOURCE DEVICE. |
| abstract | The light source (1) is a Gallium Arsenide Laser diode. A proportion of the output beam is diverted by a half mirror (10). The diverted beam is detected by a photodiode (11) which is biased by a d.c. supply via a resistor (R1). The photodiode voltage is fed via a preamplifier (PA) to the inverting input on an operational amplifier (OA). The photodiode (11), resistor (R1) and preamplifier are formed on the same substrate (26). The non-inverting input of the operational amplifier is supplied by the modulating signal (Vs). The difference voltage on the output of the operational amplifier is fed to the base of a transistor (TR) which drives the laser diode (1). |
