Description

A kind of reflection lens one-shot declines light spatial temporal monitoring device
Technical field
The present invention relates to micro-light sensing device, specifically a kind of reflection lens one-shot declines light spatial temporal prison Measurement equipment.
Background technology
Along with development in science and technology, the demand of micro light detecting is occurred gradually over all trades and professions, is no longer limited to tradition Optical field.Such as: the communications industry in order to promote the optical-fibre communications of high bandwidth, need 1310nm and Faint optical signal at the conventional optical-fibre communications wavelength of 1550nm two detects;Automatization's industry is in order to use Optical sensor detects, and needs to detect corresponding faint optical signal;Biomedical industry is in order to use In human body transmission window, the infrared light of wavelength carries out internal lesions observation, supervision, needs to carry out faint optical signal Detection;Security protection industry night monitoring for convenience, needs to carry out the faint light detection of infrared band.Application Example is too numerous to enumerate.
At semicon industry, commonly used infrared micro light detecting carries out the researchs such as failure analysis to chip.? In CMOS, a kind of effect being called hot carrier luminous can cause photon to be launched in the transistor.Conduction is logical Carrier in road accelerates under electric field action between source electrode and drain electrode, arrives its energy after the pinch off region of channel edge Amount is assisted to be converted into photon by phonon and is discharged.The spectral distribution launching photon is determined by Electron energy distribution Fixed, the latter is affected by various factors in conductive channel, widely dispersed.Emission spectrum is from visible light wave range Extending to far infrared band, peak value is probably at about the 1.4um of mid-infrared.Due to current convergence or The position photon emission intensity of voltage jump is very strong, this phenomenon have been used for semiconductor failure location, In research.In properly functioning chip, the photon that transistor discharges is the faintest, is difficult to be connect by instrument Receive.But, the release of these photons is associated with the break-make of transistor, can reflect that chip internal is transported The information of line program, has therefore been utilized in the side-channel attack of encryption chip.
Carry out transistor luminescence in chip on spatial domain (taking pictures to position interested to large-area region Sensing point), and the detection (being monitored obtaining light intensity-time curve to certain luminescence put) in time domain, The luminescence intensity time distribution of certain luminous point can be obtained while obtaining the distribution of sample emitting space.? In existing detection scheme, Si base CCD and InGaAs base APD both sensors sensitive wave band have weight Folded part.CCD has sensitivity, APD to have sensitivity at more than 900nm below 1200nm wavelength.Make Carry out partial wave with dichroic mirror and can only use a kind of sensor in 900nm 1200nm wave-length coverage, another The performance planted is wasted.But chip light emitting crest is closer to long wave end, according to condition unusual 1400nm adnexa fluctuates.No matter use which kind of sensor detection 900nm 1200nm wave band, all can make Acquisition time/the number of times of another kind of sensor is greatly increased.Even if having done compromise use 1000nm partial wave so that The collection as far as possible making two sensors equalizes, and APD end remains a need for the repeated acquisition of up to a million times and just can be compared Good signal to noise ratio, CCD end needs the time exposure of tens to hundreds of second.
Utility model content
The purpose of this utility model is to solve above-mentioned technical problem, it is provided that a kind of reflection lens one-shot declines light Spatial temporal monitoring device, this equipment further increases the system sensitivity to low light level sample, can shorten The signals collecting time, strengthen the acquisition capacity to more weak signal.
Realizing the technical solution of the utility model is: a kind of reflection lens one-shot declines light spatial temporal monitoring device, It is characterized in that: include ray-collecting parts, reflecting mirror, image-forming block and light intensity sensing parts;Described light Line collecting part is near sample, and the light sent by sample is collected and suitable process, is then passed by light Parts are sensed to image-forming block or light intensity;Near described reflecting mirror light path after ray-collecting parts, to light The light that line collecting part is given deflects, and is directed to image-forming block or light intensity sensing parts.
Described ray-collecting parts can be that amplification is more than one or is less than the optical system of.
Described reflecting mirror is completely reflecting mirror, reflects the light in big wave-length coverage.
Described reflecting mirror is including at least one of galvanometer, slide wheel, deflecting mirror.
There is rotating shaft one end of described reflecting mirror, makes reflecting mirror conveniently enter or withdraw from light path;Carry out imaging acquisition When, reflecting mirror withdraws from light path, and light is imaged parts and accepts to be exposed imaging;Gather light intensity-time The when of curve, reflecting mirror enters light path, light reflexes to light intensity sensing parts, carries out intensity collection.
Described image-forming block is including at least one of ccd sensor, Si based sensor or InGeAs sensor.
Described light intensity sensing parts are including at least one of APD, PIN photodiode, photomultiplier tube.
The beneficial effects of the utility model are:
This utility model uses completely reflecting mirror to carry out light path switching, and the light making sample send can transmit with all-wave length Parts are sensed to image-forming block or light intensity, the fully utilized sensitive wavelength scope of two part of devices, enter one Step improves the system sensitivity to low light level sample, can shorten the signals collecting time, strengthens more weak signal Acquisition capacity.
